Analytical Chemistry Testing Services

ALG offers our clients full product chemistry analysis, including chemical characterization of active ingredients, testing of product-specific impurities, physical chemistry analysis and storage stability testing. Our product chemistry testing capabilities include a broad range of antimicrobial active ingredients (AIs) and preservatives using a variety of analytical equipment such as HPLC, GC and autotitrators.

In addition to chemical characterization and physical chemistry tests, Analytical Lab Group is positioned to detect chemical residuals to support your cleaning validation needs. Common chemical residuals that Analytical Lab Group can detect include:

  • Residual Carbohydrate
  • Residual Protein
  • Residual Hemoglobin

All test labs GLP/GMP compliant
