Signal & structure
ILLUSTRATIVE RP-HPLC VISUAL
The right test.
The right evidence.
Analytical methods answer different questions. We make it clear which results you requested, what was measured, and what those numbers actually mean.
Purity analysis
Reverse-phase HPLC with UV detection and integrated peak-area percentage. A purity signal, not a claim of total peptide mass per vial.
Identity & mass
LC-MS measurement and comparison with expected molecular mass, with the laboratory's reported mass convention and method.
Endotoxin testing
Quantitative bacterial endotoxin testing, with reported units, applicable controls, dilution details and test-specific limits when supported.
Clear from intake
to interpretation.
One request, one sample accession, one auditable report trail. You can see what stage your submission has reached.
Register.
Enter material, lot number, nominal mass and your chosen panel. Review the quote and shipping instructions before sending anything.
Analyse.
Your received sample is coordinated with an independent testing partner. Progress is tracked from sample arrival through lab review.
Verify.
A reviewed PepTest analytical report carries its own reference, revision and public verification status.
Not just a
PDF. A record.
Every issued report is linked to a sample and private original laboratory evidence. Drafts stay private. Revisions and withdrawals have visible status so outdated reports cannot masquerade as current.
