Pharmaceutical Testing Services:
Eureka’s pharmaceutical stability testing helps verify the stability of products and detect any alteration in the potency, functionality and safety of pharmaceutical drug ingredients, intermediates and products after regulated storage.
Stability testing enables the assessment of the stability of the active pharmaceutical ingredient (API) or drug product under the effects of various environmental conditions, including light, humidity, and temperature. Retest intervals, suggested storage settings, and shelf life can all be determined with the help of data from these investigations.
Why is stability testing important?
Pharmaceutical stability testing is important for determining factors such as a product’s shelf life, optimal storage conditions, retest period, and assuring customers of its overall quality. During a stability test, manufacturers observe their product for any changes in the physical, chemical, biological, and microbiological makeup of the product. These elements may impact the safety and efficacy of the product for the consumer, so it is vital to conduct extensive testing before putting a drug or cosmetic on the market.
Our biopharma stability experts follow ICH guidelines, including Q5C, “Quality of Biotechnological Products: Stability Testing of Biotechnological/Biological Products,” Q1A (R2), and ICH Q6B, to provide regulatory-driven stability data for biologic and regulatory submissions. To meet your stability outsourcing needs, we offer a wide variety of protein analysis methods carried out following compliance with Good Manufacturing Practice (GMP) conditions. We offer completely qualified environmental chambers, refrigerators, and freezers with continuous monitoring and backup systems, all connected to a network of stable storage facilities that complies with GMP regulations.
GMP pharmaceutical impurity testing, analysis, and identification to meet the ICH Q3A and Q3B guidelines criteria and services for drug process impurities, residual solvents, genotoxic impurities, elemental impurities, contaminants, extractables or leachables.
Pharmaceutical impurities can originate from a variety of sources, such as leachables, degradation products, reagents, catalysts, solvents, intermediates, and excipients, together with associated contaminants. These could be elemental, inorganic, or process- or drug-related organic contaminants.
Key examples at the moment are impurities related to nitrosamines, such as NDMA, which the US FDA has identified as a concern and which is assumed to be a byproduct of the production process.
In addition to offering analysis expertise for resolving extractables and leachables, elemental impurities testing, residual solvents (OVI or VOC) analysis, or process-related impurities, our scientists are skilled at method development and validation of appropriate analytical procedures. They routinely overcome the challenges of low detection levels and difficult matrices. Furthermore, we provide extremely sensitive and specialized method development and validation experience to handle genotoxic impurity control and determination, including nitrosamines.
Guideline for Elemental Impurities:
The guideline for elemental impurities in pharmaceuticals is provided by the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH).
ICH Q3D provides recommendations on the control of elemental impurities in drug products to ensure their safety and quality. Elemental impurities can arise from various sources, such as raw materials, excipients, manufacturing processes, and packaging components.
The specific guideline is known as ICH Q3D, titled “Guideline for Elemental Impurities,” and provides an international standard for testing metals in the member regions of Europe, the USA, and Japan.
These guidelines for the determination of heavy metals have been integrated into the American Pharmacopeia (USP/NF) in chapters <232> and <233>. For the European Pharmacopeia (Ph.Eur.), these guidelines appear in chapters 5.20 “Elemental impurities” and 2.4.20 “Determination of elemental impurities.”
The previously used visual test from the corresponding pharmacopeias (e.g. USP <231>, Ph.Eur. 2.4.8) has thus been replaced by modern methods using instruments such as the ICP-MS and/or ICP-OES.
Concerns about nitrosamine contaminants, including N-Nitrosodimethylamine (NDMA), have been raised by the US FDA and other regulatory bodies. To ensure patient safety and regulatory compliance, it is imperative that pharmaceutical products undergo sensitive and accurate testing to identify and measure harmful contaminants. For the purpose of detecting traces of nitrosamines, taking the necessary action to lessen their presence, and preserving the integrity of pharmaceutical products, the accuracy of such testing is essential.
The discovery of the genotoxic contaminant N-Nitrosodimethylamine (NDMA) at low levels in a few medications caused the pharmaceutical industry great alarm. The EU reviews have identified a number of root causes leading to the presence of nitrosamines in medicines, all of which have in common a reaction of a secondary or tertiary amine with a nitrosating agent that leads to the formation of an N-nitrosamine. Frequently, the nitrosating agent was found to be sodium nitrite, often under acidic conditions during manufacture of the active pharmaceutical ingredient (API).
Although nitrosamine impurities have been discovered in only a few drug products, and batches of those products have been recalled due to unacceptable levels of these impurities, nitrosamine impurities may exist in other APIs and drug products as a result of the use of certain processes and materials that can produce nitrosamines.
Potential nitrosamine impurities have also been identified in terms of N-nitroso-dimethylamine (NDMA), N-nitroso-diethyl amine (NDEA), N-nitroso-N-methyl-4-aminobutanoic acid (NMBA), N-nitroso-iso-propyl ethyl amine (NIPEA), N-nitroso-di-isopropyl amine (NDIPA), N-nitroso-dibutyl amine (NDBA), N-ethyl-N-nitroso-2-propanamine (NEIPA), N-nitroso-di-n-propylamine (NDPA) N-nitroso-methyl-phenylamine (NMPA).
The FDA has been working closely with industry to ensure products entering the market do not contain these impurities in the future, while establishing suitable analytical methods to determine acceptable levels of these nitrosamine impurities and establish interim limits. In September 2019, the EMA began a review under Article 5(3) of Regulation (EC) No. 726/2004 to provide guidance to marketing authorization holders on how to avoid the presence of nitrosamine impurities in human medicines.
Our professionals have extensive experience offering analytical services in compliance with FDA GC-MS, GC-MS/MS, LC-MS/MS, and LC-HRMS methods. This includes carrying out the necessary method validations where the data is suitable for supporting regulatory submissions or API or drug product quality assessments.
Extractables and Leachables testing is a method used in a variety of sectors, most notably pharmaceuticals and packaging, to verify product safety and quality. Here’s the breakdown:
Extractables : Chemical substances that can be extracted from a material in a lab setting are known as extractables. The possibility for contaminants, additives, or degradation products to transfer from the material into the product it comes into contact with, can be found in them. In extractables testing, several extraction solvents and conditions are applied to the material in order to mimic real-world use and determine which components can potentially seep out.
Leachables : Materials that, under typical usage circumstances, migrate into the product or formulation they are brought into contact with. Leachables, in contrast to extractables, are assessed in real-world settings with respect to temperature, time, and pH. They may originate from plasticizers, dyes, metal catalysts, polymers and degradation products, among other substances. In the case of biopharmaceuticals in particular, these could accelerate the drug’s degradation while also potentially posing a toxicological concern. Leachable testing seeks to locate and measure any materials that might be dangerous for the product’s quality or safety for consumers.
Testing for extractables and leachables is essential for identifying and quantifying potentially hazardous leachable impurities that could leak out of pharmaceutical container closure systems and contaminate a drug, endanger patient safety, or result in serious quality problems.
Regulatory expectations for Extractables and Leachables Analysis:
Regulatory expectations vary depending on the industry and the specific product being evaluated. However, there are some common principles and guidelines that are generally followed :
  • ICH Guidelines : The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) has provided guidelines for pharmaceuticals, including ICH Q3D for elemental impurities and ICH Q7 for Good Manufacturing Practice (GMP).
  • FDA Guidance : The U.S. Food and Drug Administration (FDA) provides guidance documents for pharmaceuticals, medical devices, and other regulated products. For example, FDA Guidance for Industry on Bioanalytical Method Validation outlines expectations for validation of analytical methods used to assess the identity, strength, quality, purity, and potency of biological drug products.
  • USP General Chapters : The United States Pharmacopeia (USP) publishes general chapters that provide standards for the pharmaceutical industry. USP <1663> and USP <1664> are specifically related to extractables and leachables testing.
  • EU Directives : In the European Union, directives such as EU Directive 2009/48/EC on the safety of toys and EU Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment may apply to extractables and leachables analysis.
  • ISO Standards: International Organization for Standardization (ISO) standards such as ISO 10993 for biological evaluation of medical devices and ISO 18562 for biocompatibility evaluation of breathing gas pathways in healthcare applications may also provide guidance.
  • Industry Best Practices : Many industries have developed their own best practices and guidelines for extractable and leachable analysis. For example, the Parenteral Drug Association (PDA) publishes technical reports and guides related to pharmaceutical manufacturing and quality assurance.
Overall, compliance with relevant regulations and guidelines is essential to ensure the safety and efficacy of products and to meet regulatory requirements for market approval.
Eureka offers extractables and leachables testing services through our GMP-compliant laboratory located in Delhi/NCR with research support facilities as part of our commitment to total quality assurance. Different analytical techniques are employed in extractables and leachables analysis to identify and quantify substances that may leach into the product itself from packaging materials, medical devices, or other products. Among the often-used methods are nuclear magnetic resonance (NMR) spectroscopy, Fourier-transform infrared spectroscopy (FTIR), inductively coupled plasma mass spectrometry (ICP-MS), gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS).
Microbiology testing is critical to ensuring sterility of your product and to determine antimicrobial effectiveness, as well as identifying microorganisms and potential contamination.
Accurate analysis of contaminants and impurities in biotechnology products is necessary during product characterization in order to help you comply with ICH Q6B recommendations. Our range of services and methods includes the characterization of contaminants and impurities in products obtained from biotechnology.
Our solutions include:
  • Sterility Testing : Pharmaceutical laboratories conduct sterility testing to ensure that products are free from viable microorganisms. This is particularly crucial for sterile products such as injectables, ophthalmic solutions and parenteral drugs. Sterility testing involves incubating the product in culture media for a specified period under appropriate conditions and examining for microbial growth.
  • Microbial Limits Testing : Microbial Limits Testing determines the total viable aerobic microbial count present in pharmaceutical products. It ensures that products meet specified microbial limits and are free from excessive microbial contamination. This testing helps assess the cleanliness of manufacturing processes and the efficacy of preservation systems.
  • Endotoxin Testing : Endotoxin testing is performed to detect and quantify endotoxins, which are components of the cell wall of Gram-negative bacteria. Endotoxins can cause fever, shock, and other adverse reactions in humans. Often, we use Limulus Amebocyte Lysate (LAL) assays to detect endotoxin contamination in products.
  • Bioburden Testing: Bioburden testing measures the total number of viable microorganisms present on a product before sterilization. It helps assess the effectiveness of sterilization processes and is performed on raw materials, components, and in-process products.
  • Environmental Monitoring : Pharmaceutical laboratories conduct environmental monitoring to detect and control microbial contamination in manufacturing facilities. Environmental monitoring helps identify potential sources of contamination and implement corrective actions.
  • Microbial Identification : In cases where microbial contamination is detected, microbial identification techniques are used to identify the specific microorganisms present. Polymerase chain reaction (PCR) and sequencing are common methods used for microbial identification.
  • Method Validation : It is essential to validate microbial testing methods to ensure their accuracy, precision, specificity, and robustness. Method validation involves testing the method’s performance characteristics using appropriate controls and acceptance criteria.
  • Compliance with Regulatory Standards: Pharmaceutical laboratories must comply with regulatory standards such as those provided by the United States Pharmacopeia (USP), European Pharmacopeia (Ph. Eur.), and other regulatory agencies such as the FDA and EMA. Compliance ensures that microbial testing is conducted according to established guidelines and requirements.

Food allergens are typically naturally-occurring proteins in foods or derivatives of them that cause abnormal immune responses. Prevalence of food allergies around the world is believed to be increasing, with more than 8% of children and 2% of adults in different countries and having allergy to one or more foods. The most common allergens for young children are milk and egg but fortunately, many children outgrow these allergies by the time they have reached 5-7 years of age. On the other hand, allergies such as those to seafood, peanut and tree nut may develop later and are lifelong conditions. Commonly known allergens are as follows:
  • Gluten
  • Crustaceans
  • Eggs
  • Fish
  • Peanuts
  • Soybeans
  • Milk
  • Nuts
  • Celery and products thereof
  • Mustard
  • Sesame seeds
  • Sulphur dioxide and sulphites
  • Lupin and products thereof
  • Molluscs and products thereof
Eureka can help food producers to do a Food Label verification and check the label for compliance with different National and International regulations.
The basic elements on a food packaging label usually include (unless the producers are exempt from labeling their product) :
  • Statement of identity
  • The product’s net weight
  • Manufacturer’s address
  • Nutrition facts
  • This is probably the most complicated part of a food label and must usually include serving size, nutrients, vitamins and minerals
  • There are strict guidelines and less strict recommendations as to the font colors, type, size, background colors, hairlines and placement of this part of the label
  • Ingredients list
  • Some exceptions apply here as well. For example, for a single-ingredient food product, such as honey, you may not need to include an ingredients list. This is only a small example of how complex labeling regulations can be and how carefully you need to inform yourself in order to accurately present your product to the consumers
  • Allergens, if present in food, should always be listed with the ingredients. If you are making any health claims such as “fat-free” you need to make sure your claim is 100% accurate.
The quality and safety of food packaging and other food contact-related materials, is a primary concern for all consumers, businesses, and governments across the global supply chain. We offer consultation and testing on the requirements of the package materials as per IS – 9845, IS – 10171, IS – 15392 and FSSAI

Food-related regulations specify that for all packaged food items the composition and nutritional values be declared on the label. With greater ease, of making healthier food choices, the nutritional labeling testing concept developed in India and today it is mandatory that nutritional information of almost all processed foods should be displayed on food items.
Appropriate analysis and nutritional labeling are important to approve a food product for sale in the market by the government regulatory bodies. Nutritional information on the label also helps the consumers to make choices for healthy foods by comparing the nutritional ingredients between different brands. It acts as an important source of information to consumers with specific needs like infants, old aged, and also about allergens, intolerances like sugar, citrus, lactose, etc.
Nutritional facts on the product labels are mandatory on almost all food products. This follows the implementation of the FDA Nutrition Labelling and Education Act (NLEA).
Eureka offers precise and reliable analysis for Nutritional labeling and also supports label claims for manufacturers, retailers, importers, and exporters that can help with compliance, address consumer concerns and create awareness in the minds of consumers. We provide consultation on labeling requirements to help you ascertain the tests that need to be conducted for nutritional content like:
  • Calorific value
  • Energy
  • Protein
  • Vitamin
  • Mineral
  • Carbohydrate
  • Sugar
  • Fibre
  • Fats
  • Saturated Fatty Acids
  • Monounsaturated Fatty Acids
Pesticides are well-known as potentially toxic compounds to humans. Health effects may be acute or delayed in those who are exposed. Long-term exposure to pesticides may cause severe health complications, such as occupational exposure to the organic pesticide namely, rotenone has been linked with an increased risk of Parkinson’s disease. Nowadays consumption of fresh vegetables and fruits is increased in quantities but it is this fresh produce that is most vulnerable to pesticide residues. Extreme use of pesticides/fertilizers in farming for the production of excessive food products especially fruits, vegetables, and many other crops can lead to habitat loss. This leads to potential risks to food safety by entering the food chain.
Consumer concerns and government regulations are increasingly focusing on the safety of foods. However, there are many regulatory hurdles and strategic difficulties that can cause costly time-to-market delays in the industry. Our experts can help you to overcome these challenges through analysis and implementation of our Quality Assurance expertise. Pesticide residue analysis identifies the residue levels in food products by performing standard chemical and microbiological tests by giving food manufacturers, producers, and exporters assurance of their product ingredients.
At Eureka, we offer reliable, accurate, and well-established quantitative methods to meet the needs of industry and government, in an effort to ensure a safe and reliable food supply. We lay emphasis on the most sensitive techniques for sample preparation and testing to overcome the significant challenge of detecting “low levels of these chemicals” in complex matrices by performing express analytics within 24-48 hour-testing
We perform chromatographic techniques such as LC/MS/MS and GC/MS/MS systems and all methods have been developed and validated in compliance with the latest USFDA, CODEX, and other national and international requirements for rapid screening of pesticide residues in various foodstuffs.

Food contaminants are well-defined as spoiled or tainted foods because they either contain microorganisms, such as bacteria or parasites, or toxic substances that make them unfit for consumption. A food contaminant can be either biological, chemical, or physical in nature, with the former being more common. These contaminants have several routes throughout the supply chain (farm to fork) to enter which makes the food product unfit for consumption.
It is evidently acknowledged, “food contamination that occurs in one place may affect the health of consumers living on the other side of the planet”. Contamination issues are volatile both in terms of their nature and size, and as such can be costly in terms of lost productivity and vastly negotiated timeframes. An initial solution for the contamination issue is mandatory, it is essential that the solution is long-lasting and that confidence to restore the ongoing productivity.
Contamination of fresh produce is emerging as a major food safety challenge. Eureka’s expertise is well experienced in identifying a wide range of contamination occurring from production lines to processes. Our team offers precise and reliable contamination testing and identification by using analytical techniques such as HPLC, GC, GC-MS, LC-MS-MS, GC-MS-MS, GC-HS-MS, ICP-OES, ICP-MS, FTIR, ELISA, PCR, UV-VIS, NMR and much more accordingly. The contamination testing laboratory has vast experience and expert insight quickly determines the accurate analytical approach to employ to solve a wide range of contamination issues faced by customers, exporters & manufacturers.
Our testing service can determine trace levels of contaminants which includes,
  • Melamine
  • Residues
  • Heavy Metals
  • Dioxins
  • GMO
  • Mycotoxins and more
It is mandatory for a food producer to declare a “best before” or “use by” date for “safety” and “health” reasons. The “health” reason is applicable to food that is intended by the manufacturer to form the sole source of nutrition for a person’s diet for a specified period. This will apply where storage affects the critical nutrient profile of products such as infant formula or special dietary foods manufactured to provide the sole source of nutrition to persons who are ill or are unable to eat normal foods.
The “safety” reason is applicable to food that can become microbiologically unsafe before the food noticeably spoils. This will not apply to shelf-stable, frozen or most raw foods but may apply to certain chilled ready-to-eat foods, for example, chilled meals and salads. The development of “use by” dates for safety reasons is discussed below. A “best before” date is applicable to food where deterioration affects consumer acceptance without impacting health and safety. Many product changes will affect consumer acceptance, including:
  • Organoleptic properties
  • Rancidity
  • Texture changes
  • Moisture loss
  • Moisture gain
  • Staling
  • Flavor loss
  • Light induced changes
  • Microbial spoilage
Species identification in food products has been the subject of an increasing number of reports because of its importance in food authentication and due to major advances in analytical methods.
Species identification is an important part in food authentication for several reasons, such as food safety, food choice, and religious practices. The presence of non-declared protein may have serious health consequences for persons suffering from an allergy. Animal-derived ingredients have to be absent in foods for vegetarians and vegans.
DNA Barcoding
Species identification has traditionally been based on morphological data and implemented in dichotomous identification keys. With easy access to increasingly affordable DNA sequencing, specimens can also be identified through sequence similarity in taxonomically curated sequence databases. Even a very short stretch of DNA can be sufficiently informative to enable the clustering of conspecific species. A single molecular marker is therefore often sufficient for DNA “barcoding,” where a unique sequence of a particular marker is referred to as a species barcode.
Food sensory analysis is the use of the human senses to objectively analyze foods – for properties such as taste, flavor and texture. It is used in assessing the quality of products, troubleshooting problems and new product development.
What does the food actually look and taste like? Describing the taste of a food in a scientific way that can be interpreted by others and then using this to improve product quality in some way is a valuable and perhaps under–appreciated technique. Sensory analysis can be broken down into three sub-sections:
  • Analytical testing (dealing with objective facts about products)
  • Affective testing (dealing with subjective facts such as preferences)
  • Perception (the biochemical and psychological aspects of sensation)
Eureka has a team of experienced food tasters who can evaluate the flavor, odour and texture characteristics of products. Advanced statistical analysis then allows products to be grouped, and their similarities and differences quantified. These analyses can also be ‘checked’ as per customer’s Internal document and/ or National and International document to verify if the product meets requirements.
