HPLC Testing Services
High-Performance Liquid Chromatography for active ingredient quantification, purity, and identity.
HPLC (High-Performance Liquid Chromatography) testing separates, identifies, and quantifies individual chemical compounds in complex mixtures, making it the gold standard for active ingredient potency verification, purity profiling, and label claim validation in dietary supplements and cosmetics.
High-Performance Liquid Chromatography (HPLC) is the gold standard for quantifying active ingredients in dietary supplements, cosmetics, and foods. Qalitex Laboratories uses HPLC systems including RP-HPLC, UHPLC, and HPLC-UV/DAD to deliver precise, validated results for identity, potency, purity, and impurity profiling.
