Help & FAQ

General

Verifypeps provides independent analytical testing for research and verification. Certificates summarise methods, results, and QC checks for the sample as received. See our Research Use Only policy and laboratory partner disclosure.

Verification & Security

Each certificate includes a unique ID and QR link to our public registry lookup page. Anyone can confirm that displayed data matches our registry record at the time of lookup. This confirms record consistency only—not product safety or suitability for any use.

Process

Register your batch in the Lab Portal, ship your sample to the UK intake address provided at order acceptance, and track status in your account. Selected HPLC methods may be performed by EU partner laboratories—see our laboratory partner disclosure.

Key metrics on certificates may include mass accuracy, resolution, tailing factor, and theoretical plates — referenced against the method and suitability criteria for that run.

Understanding Your Certificate

Key Quality Metrics

Purity is typically reported as area percent from the integrated HPLC trace. Identity confirmation uses LC-MS with ppm error on the expected mass.

Chromatogram

The UV trace shows detected peaks vs time. System peaks and integration regions are defined in the method.

System Suitability Table

Summarises criteria such as resolution and peak symmetry checked before sample sequences.

Glossary of Key Terms

PPI

Peak purity index — indicator of peak homogeneity at the detection wavelength.

EU/mL

Endotoxin units per millilitre — reported for LAL assays.
