Independent analytical testing for research peptides and compounds
PureAssay Laboratories provides precision HPLC purity analysis, mass spectrometry identity confirmation, and quantitative assay testing. We deliver verifiable certificates of analysis to support peptide suppliers, distributors, and research organizations across Canada and globally.
Comprehensive testing capabilities
We offer rigorous, third-party analytical solutions designed to verify chemical integrity, purity levels, and molecular identity prior to distribution or experimental application.
HPLC purity analysis
High-resolution reversed-phase HPLC testing to quantify compound purity and accurately identify trace organic impurities.
Mass spectrometry
Definitive molecular mass and sequence confirmation using LC-MS instrumentation to verify absolute compound identity.
Quantitative assay
Accurate net peptide content and concentration measurements to verify lot consistency and correct dosage specifications.
Certificate of Analysis
Clear, tamper-evident reporting complete with raw chromatograms, spectrum readouts, and analyst sign-offs for full transparency.
Uncompromising scientific rigor and transparency
Operating out of Mississauga, Ontario, PureAssay Laboratories was established to serve as an objective benchmark in peptide quality assurance. Because we do not manufacture or sell compounds, our analyses remain strictly unbiased, providing researchers and distributors with dependable data they can present to the scientific community with total confidence.
A structured, reproducible submission workflow
From secure sample intake and chain-of-custody logging to instrument calibration and final analytical reporting, our process is optimized for speed, precision, and complete traceability.
"PureAssay has become our primary testing partner. The chromatographic clarity and detailed LC-MS reports provide our customers with unquestionable proof of quality."
Research peptide distributor
"Turnaround times are consistently rapid, and having direct access to their analytical chemists when reviewing complex spectra is an invaluable advantage."
Biochemical research group
"Their rigorous third-party verification caught formulation discrepancies early, protecting our research timeline and maintaining our strict laboratory standards."
