The instrumentation behind every certificate
Each assay answers a different question. Most release programmes pair purity with identity and net content, then add contamination panels where the application demands them.
RP-HPLC / UV-DAD
Purity
Reverse-phase gradient separation with diode-array detection. Reports main-peak area percent and resolves related substances down to 0.05% area.
LC-MS (ESI-QTOF)
Identity Confirmation
Monoisotopic mass confirmation against the theoretical sequence mass, with charge-state deconvolution and mass-accuracy reporting in ppm.

Ship Samples
Send crimped, unopened vials to the laboratory quoting your order number. Every vial is photographed and inspected on arrival.
- 03
Laboratory Analysis
Your samples are analysed on qualified instrumentation under documented methods, with full chain-of-custody from receipt to report.
- 04
Certificate Issued
Results are reviewed and signed by a second analyst. Your Certificate of Analysis is released with a unique number and QR code.
- 05
Verify Online
Anyone holding your certificate can confirm its authenticity instantly - scan the QR code or enter the certificate number.
A certificate nobody can fake, and nobody can browse
Every certificate carries a unique number and a QR code. Scanning it returns that one certificate straight from our records, so an altered PDF gives itself away immediately.
There is no public directory of our certificates and no way to list them. A certificate can only be retrieved by someone who already holds its number or its QR code.

Knowledge baseThird-Party Peptide Testing: A Complete Guide
What independent testing covers, which assay answers which question, and what a Certificate of Analysis can and cannot tell you.
How to Read a Certificate of Analysis
What each section of a COA tells you, which numbers matter, and the three most common ways a report gets misread.
How Certificate of Analysis Verification Works
How QR and certificate-number verification let you detect an altered report, and why a public directory of certificates would be a confidentiality failure.
Peptide Testing Methods Explained
How each instrument works, what it can measure, and where its limits are. Written for people commissioning the work, not operating it.
We moved our entire release testing programme to LAVA after a competitor's report failed to reconcile with our own retained samples. Two years on, every batch we have cross-checked has matched their numbers.
The QR verification changed how our customers treat our documentation. They stopped asking whether the COA was real, because they can check it themselves in about four seconds.
What we value is the honesty. When a batch came back at 94% against a 99% label claim, LAVA reported 94% and gave us the chromatogram to prove it. That is exactly what an independent laboratory is for.
