Peptide certificates of analysis you can verify
PrimeCOA is an independent HPLC and LC-MS testing laboratory built specifically around research peptides — identity, purity, and safety data for manufacturers and researchers who need results they can verify, not just trust.
Testing built on rigor
Every sample runs through validated methods, independent review, and full chromatographic traceability before a certificate is ever issued.
Identity Confirmation
HPLC-UV and LC-MS identity confirmation verifying retention time, spectral match, and molecular weight against certified reference standards.
Purity & Net Peptide Content
Quantify percent purity and net peptide content, accounting for salts, moisture, and counter-ions that can inflate labeled vial weight.
Endotoxin & Sterility Screening
LAL endotoxin testing and bioburden/sterility screening for research compounds intended for reconstitution.
Heavy Metal & Contaminant Screening
Detection of residual solvents, heavy metals, and synthesis byproducts that fall outside acceptable thresholds.
Stability & Reconstitution Testing
Degradation and stability profiles under defined storage conditions, including behavior after reconstitution.
Certificate Issuance
A lab-signed COA with a unique accession number and QR verification code, traceable to raw chromatographic data.
