Analytical Testing Laboratory
Precision Testing for Peptides
Purity, sterility, endotoxin, and heavy metal analysis for manufacturers, research labs, and compounding pharmacies — so you can release product with confidence.
Our Core Testing Services
Four essential analyses to characterize, qualify, and release your peptide products.
Purity Testing
Quantify peptide content and resolve impurities by reverse-phase HPLC, with optional LC-MS mass confirmation.
Sterility Testing
Confirm the absence of viable microbial contamination following USP <71> methodology.
Endotoxin Testing
Detect and quantify bacterial endotoxins (LAL / BET, USP <85>) against your endotoxin limit.
Heavy Metal Testing
Measure elemental impurities such as lead, arsenic, cadmium, and mercury by ICP-MS per USP <232>/<233>.
