KB Analytical runs HPLC purity, mass-spec identity, and label-claim quantification on peptides and research compounds — then publishes every certificate to a public registry anyone can verify.
What every KB Analytical report answers
No single instrument proves everything. We combine separation, identity, and quantitation so a result can’t hide a problem.
Reverse-phase HPLC with UV detection separates the target from related impurities. Purity is the main-peak area as a percentage of everything detected.
Mass spectrometry confirms the molecule is what the label claims by matching its exact mass — and surfaces impurities that UV alone can miss.
Against a calibrated reference standard we measure how many milligrams are actually in the vial versus the label claim — the number vendors can’t fake.
Pick your compound and services. You’ll get an order reference and submission details.
Mail the vial with your reference inside. Discreet, plain packaging — no product details on the outside.
HPLC, LC-MS, and quantitation run against calibrated standards. Typical turnaround is 5–12 business days.
Your certificate posts to the public registry, so any buyer can confirm it’s genuine.
Every result lives in a public registry keyed to a unique certificate ID. A buyer types the ID, and the purity, identity, and content shown must match the PDF exactly. A fabricated report simply won’t resolve.

A certificate of analysis (COA) listing chromatographic purity, mass-spec identity confirmation, and measured content versus label claim — plus a public registry link so anyone can verify it.
One sealed vial of the finished product is enough for HPLC + LC-MS + quantification. For blends we may ask for a second vial.
Certificates are published to the public registry by default — that’s what makes them verifiable. Ask us if you need a private test.
Our core menu is purity, identity, and content. Contamination panels are available as add-ons on select compounds — ask before shipping.
Order in minutes, ship your vial, and get a certificate the whole community can verify.
