Analytical methods we run.
HPLC Purity Analysis
High-Performance Liquid Chromatography with calibrated reference standards. Determines exact purity percentage and flags impurities or byproducts.
Mass Spectrometry
Confirms molecular identity and exact molecular weight. Detects unexpected fragments or wrong sequences.
Endotoxin Testing
Limulus amebocyte lysate (LAL) assay confirms endotoxin levels are below research-grade thresholds.
Stability & Reconstitution
Ongoing stability studies under controlled lab-light conditions. Guidance for solvent, ratio, and storage parameters.
For supplier and institutional inquiries
Polaris Analytical works with research peptide suppliers, university labs, and institutional research centers requiring independent third-party COA generation.
