Impurity Testing & Identification

Let our deformulation and failure analysis experts isolate and identify any impurities or unknown compounds in your product or raw materials

Avomeen’s GMP compliant laboratories specialize in unknown material analysis of contaminants, impurities, trace materials, and residuals within a sample or product. Our scientists can also test for product degradation over time and identify any process impurities present.

Manufacturers take advantage of Avomeen’s impurity testing services to verify that the ingredients from their suppliers meet their quality requirements.  Those that have their product produced by third parties frequently use our services to check that their products active ingredients remain present and at the proper levels through batch-to-batch or good vs bad sample testing performed over time.

Don’t risk your product or company’s reputation, the presence of an unknown component or impurity can cause not only product performance issues, but can also undermine the safety of your product.  Contaminants can come from many different sources including active ingredients, fillers, reagents, catalysts, solvents, intermediates, excipients, degradation products, and more.  We can determine the source of the impurity and help you develop a resolution.

Our purity testing laboratory can isolate, characterize, and identify unknown materials and components.  Once the impurity is identified we can determine a method to remove the impurities from your product.  To test for degradants and other product impurities we use a variety of instrumentation and techniques including FT-IR, NMR, LC/MS, GC/MS, ICP-MS and LC/MS.
