Peptide Testing Services
Every service below is backed by validated methodology, independent quality review, and a signed certificate of analysis you can trace back to source data.
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
Percent purity by HPLC-UV area, plus net peptide content that accounts for salts, moisture, and counter-ions inflating labeled vial weight.
Endotoxin & Sterility Screening
LAL endotoxin testing and bioburden/sterility screening for research compounds intended for reconstitution and injection-format research use.
Heavy Metal & Contaminant Screening
Detection of residual solvents, heavy metals, and synthesis byproducts that may be present at levels outside acceptable thresholds.
Stability & Reconstitution Testing
Time-course degradation studies under controlled temperature, light, and humidity, including behavior after reconstitution.
Custom Method Development
For peptides without an established protocol, our analysts develop and validate a custom HPLC or LC-MS method before running production samples.
pH & Solubility Testing
Confirmation of solution pH and solubility behavior to flag formulation issues before a compound reaches a researcher's bench.
Certificate of Analysis Issuance
A clear, lab-signed COA with a unique accession number and QR verification code, traceable back to the underlying chromatographic data.
