CHARTERBioanalytics
Independent · Method-Validated · Audit-Ready

The lab your customers ask about.

Charter Bioanalytics is an independent third-party laboratory for peptide identity, purity, mass, and endotoxin testing. Every report is method-validated per ICH Q2(R1), USP <85>, and ISO/IEC 17025 principles — designed for traceability, not just a number on a page.

What we test

Four assays. One report. Built for audit.

Every Charter report carries the same structural integrity — identity, purity, mass accuracy, and endotoxin — graded against published thresholds, with per-criterion verdicts and a clear audit trail.

P

Identity & Purity

RP-HPLC with diode-array detection, n=3. Retention-time match against reference standard. Purity reported to three decimals. Threshold: ≥ 99.0% PASS · 95.0–98.99% CAUTION · <95.0% FAIL.

M

Mass Verification

Gravimetric per-vial assay, n=3, calibrated balance. Result reported as measured / labelled (% delta). Tolerance: ±10% PASS, >+10% OVERFILL (not a safety flag), <−10% UNDERFILL (dosing risk).

E

Endotoxin (LAL)

Kinetic chromogenic LAL via Lonza Endosafe nexgen-PTS. Method per USP <85> / EP 2.6.14. Threshold: < 0.5 EU/mg for parenteral-grade research material.

Why Charter

Built for the question, not the asterisk.

Other labs return a number. Charter returns a verdict — graded against published thresholds, with per-criterion chips, traceable methods, and an authentication ID on every report.

When a customer asks “is this real?”, we want the answer to be one click and one read.

  • Tiered verdicts. Green hero only when identity confirms and purity passes integrity floor.
  • OVERFILL is labeled. Above-tolerance mass gets an amber pill — not red — because more isn't dangerous.
  • Endotoxin-only reports stand alone. Single-test submissions get a dedicated design, not a partial-fail look.
  • LOT-traceable. Every report verifiable at charterbioanalytics.com/verify.
