Independent analytical testing for research peptides
PureAssay Laboratories delivers precise third-party HPLC purity analysis, mass spectrometry identity confirmation, and quantitative assays. Protect your research, verify supplier claims, and receive an authoritative Certificate of Analysis for every batch.
Our core analytical services
We provide Canadian research institutions, peptide suppliers, and distributors with uncompromising analytical precision. Order individual tests or bundle them to verify product integrity from raw material to finished vial.
HPLC purity analysis
High-Performance Liquid Chromatography separates compound components to accurately determine purity percentages and detect trace degradation or synthesis impurities. Each report includes your full, unabridged chromatogram.
Mass spectrometry
Confirm precise molecular identity and guard against supplier substitution. We measure observed molecular weight directly against expected theoretical values to verify that your peptide or compound is exactly what was ordered.
Quantitative assay
Assess active ingredient net weight and confirm content against label claims. Our quantitative assay testing flags underdosed or mislabeled vials, ensuring exact concentration consistency for your research clients.
Rigorous third-party verification that eliminates supplier risk
Selling or researching unverified compounds creates critical vulnerabilities, from impure syntheses to supplier fraud and marketplace rejections. PureAssay provides independent, conflict-free verification that safeguards your business reputation and guarantees reliable scientific outcomes.
Comprehensive Certificate of Analysis
Every sample tested at our Mississauga laboratory yields a comprehensive Certificate of Analysis (CoA). Your report includes the exact product name, lot number, complete HPLC chromatogram, mass spectrometry spectrum comparing theoretical and observed molecular weights, assay results versus specification, clear pass/fail outcomes, certified testing dates, and sign-off by our laboratory personnel.
The Complete Verification Panel
Our bundled Complete Verification Panel combines HPLC purity testing, mass spectrometry identity confirmation, and quantitative content assay into a single efficient workflow. Upon sample intake, our team confirms turnaround timelines and initiates thorough testing to deliver definitive validation for distributor lots and critical research batches.
