Analytical & handling terms
HPLC (high-performance liquid chromatography): a technique used to measure the purity of a peptide by separating its components. Mass spectrometry (MS): confirms a compound's identity and molecular weight. ICP-MS: screens for heavy-metal content. Endotoxin testing (e.g. LAL): measures bacterial endotoxin levels. Lyophilised: freeze-dried to a stable powder. Reconstitution: dissolving a lyophilised powder in a suitable solvent such as bacteriostatic water for laboratory use.
Certificate of Analysis (COA): a batch-specific document reporting these test results. See our Certificates of Analysis page.
