High-resolution reverse-phase HPLC and LC-MS/MS for accurate peptide purity quantification, impurity profiling, and independent COA verification. Canadian lab, mail-in samples accepted nationwide.
HPLC peptide purity testing at Cert Biohealth Testing Labs costs CAD $175–$350 per sample with a standard turnaround of 9–11 business days (rush 2–3 days available). Every report includes a chromatogram, calculated purity percentage, impurity profile with detection to 0.1%, and an impartial assessment of the supplier’s COA.
Our laboratory uses RP-HPLC with UV detection and LC-MS/MS to quantify purity, identify impurities, and verify supplier COAs. Methods are validated per ICH Q2 guidelines.
High-resolution RP-HPLC with UV detection for accurate quantification of peptide purity. Typical detection limits of 0.1% for impurities.
Liquid chromatography with tandem mass spectrometry for detailed molecular characterization and identification of peptide impurities.
Precise quantification of target peptide purity using validated HPLC methods with multiple detection wavelengths.
Identification and characterization of deletion sequences, truncated peptides, and synthesis by-products.
Typically 100–500 µg of lyophilized peptide is sufficient for a full HPLC purity analysis. For combined purity and mass spec testing, we may require up to 1 mg. Contact us at info@certbiohealth.ca or +1 (416) 000-0000 for sample-specific guidance.
Standard turnaround is 9–11 business days from sample receipt. Rush 2–3 business day service is available for an additional fee. We will confirm the expected delivery date when your sample is logged in our LIMS.
HPLC purity testing quantifies the percentage of your target peptide versus all other peaks in the chromatogram. LC-MS/MS additionally confirms molecular identity and characterizes individual impurities by mass. We recommend LC-MS/MS for critical applications or when your supplier COA does not include mass spec data.
Yes — this is one of our most common requests. We run your sample independently and provide a side-by-side comparison with the supplier’s COA. In our dataset, 73% of samples show measurable discrepancies versus the supplier-reported purity.
Our RP-HPLC methods routinely detect impurities at the 0.1% level. For critical applications, our LC-MS/MS methods can detect trace impurities below 0.05% depending on the peptide matrix.
Cert Biohealth Testing Labs is based in Toronto, Ontario, and accepts mail-in samples from anywhere in Canada. Results are delivered electronically within 9–11 business days.
Our Certificate of Analysis includes: the RP-HPLC chromatogram with peak integration, percentage purity value, full impurity profile, comparison to your supplier COA, method details, and a review signed by a PhD-level analytical chemist.
Yes. We provide compounding pharmacies with batch-level purity documentation that aligns with Health Canada GMP requirements, including USP and Ph.Eur. method references where applicable.
Ship your samples for professional HPLC purity analysis. Fast turnaround, precise results, and a comprehensive Certificate of Analysis.
