Peptide identity, purity & assay — RP-HPLC-UV

Our core certificate of analysis. Reversed-phase HPLC with UV detection at 214 nm. Every COA reports identity (retention-time and UV-spectral match against a certified reference standard), chromatographic purity (area %), and assay / net-peptide content (quantified mg of peptide per vial — not just a purity %). Each COA carries a unique QR code and SHA-256 hash, verifiable at kmdanalytical.com/verify.

Pricing

Rates apply automatically to the whole order: $125/sample at 5+, $100/sample at 10+.

Multi-compound (blend) vials

A vial containing more than one active — a blend — is billed at the standard sample rate plus 50% for each active beyond the first. Each additional compound needs its own reference standard and a method that resolves it cleanly from the others, so it is genuinely more bench work than a single-compound vial.

A blend counts as one vialtoward the volume tiers, and the surcharge applies to whichever per-sample rate your order qualifies for — so a two-compound vial on a 5+ sample order is $187.50 rather than $225. Enter a blend on the order form as a single vial and use “+ Add another compound in this vial” for each additional active; the total updates automatically.

What you receive:one certificate per vial with a separate row for each active — its own identity, chromatographic purity, and mg/vial — sharing one chromatogram and one verification code. Not a combined assay.

One honest limit:a clean per-compound result depends on our method resolving your specific actives. Most combinations are fine, but some — compounds that co-elute, or several very polar actives together — cannot be separated reliably. Send us the compound list before shipping and we will confirm what we can quantify, or tell you plainly if we can't.

Turnaround & rush service

Turnaround is measured from receipt of your sample at the lab — shipping time is separate. *Surcharge applies to the order total, since rush service expedites every sample on the order. Same-day and next-day are by prior arrangement and subject to capacity; samples must be received before 10:00 AM PT for same-day service.

Add-on & à la carte services (in-house)

Bacteriostatic water can be added right on the order form — it bills at the flat $75 and counts toward your sample total, so it can move your whole order into the next rate tier. (Four peptides is $600; add bacteriostatic water and all five samples drop to the bulk rate — $575 total, with the extra test included.) Solution pH isn't part of the online total — note it on your order and we'll confirm and invoice it separately.

Current peptide panel

We can also test other peptides beyond this panel — we just need 5–7 days' prior notice to source the certified reference standard and verify the method. Our scope is RP-HPLC-UV: identity, chromatographic purity, and net-peptide assay. We don't run LC-MS, sterility, or endotoxin testing — and we'll tell you plainly when a job needs a lab that does.

Sample submission

One sealed vial per sample; include compound name, expected concentration, and any target spec.
