Raw materials testing

Offering a wide range of raw materials testing services, RSSL can support you throughout the pharmaceutical development and manufacturing process, helping you maintain your product’s integrity from raw material to market.


At RSSL, we understand that not every manufacturer has the resources, expertise or equipment available to conduct raw materials testing and interpret the results. Whether applying the pharmacopoeia monographs, transferring in your methods, or developing new methods on your behalf, we can provide GMP QC testing services for your APIs, excipients and drug products.  


Our services span chemical, physical, biopharmaceutical and microbiological testing. This includes detecting impurities in the production of raw materials containing amino acids, as outlined in Ph.Eur.2.2.56.  


In addition to conducting analyses, we can provide expert consultancy, advice on the best testing approaches and guidance on topics such as harmonisation and upcoming pharmacopeial changes.
