Pricing.

Purity & Identity — $90.00
HPLC-UV / ESI-QTOF-MS
Mission Hills, California

What each test costs, no order form required. Prices are per sample and current as published here — the same figures the order form charges, read from one configuration rather than retyped. Every certificate carries the number and the method that produced it; see Methods & instrumentation for the instruments behind these prices.

High-Performance Liquid Chromatography (HPLC) quantifies purity, Mass Spectrometry (MS) verifies structural identity by confirming exact molecular weight, and the same panel reports the labeled amount as % of label — one quality-control panel for research peptides.

What's included

Identity — Structural identity by Mass Spectrometry — confirmation of exact molecular weight. Part of the Purity & Identity panel.
Purity — Purity by High-Performance Liquid Chromatography (HPLC) — quantified against contaminants and impurities. Part of the Purity & Identity panel.
Quantity — Labeled amount, reported as % of label. Part of the Purity & Identity panel.

Add-on testing.

Priced separately from the panel
per sample · own turnaround

Add-ons run alongside the Purity & Identity panel, each on its own instrument and its own turnaround.

Add-on 01

Bacterial Endotoxins

LAL reagent endotoxin testing, determining endotoxin concentrations as low as 0.03 EU/mL, so research products can be shown free from pyrogens.

LAL (fluorometric)

Price$110.00Turnaround5 business days

Add-on 02

Elemental Impurities (Heavy Metals)

Heavy-metals screening by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), a highly sensitive technique for detecting and quantifying trace heavy metals. We screen for lead, mercury, arsenic, and cadmium — the standard for guarding against toxic metal contamination.

ICP-MS

Add-on 03

Sterility

USP ⟨71⟩ sterility testing: samples are inoculated into two growth media and incubated a minimum of 14 days, then inspected to verify the product is sterile.

Bacterial culture (USP ⟨71⟩)

Price$250.00Turnaround13 business days

Sterility is temporarily not available — listed for reference, not orderable.

Blend pricing.

One vial, several peptides
first analyte + $20.00 each after

A blend vial carries several peptides at their own labeled amounts. The Purity & Identity panel ($90.00) covers the first analyte; every additional analyte on that same vial adds $20.00 — reported with its own purity, identity, and % of its own labeled amount on the same certificate.

Worked example — a 4-peptide blend, one vial

Purity & Identity panel · first analyte: $90.00
3 additional analytes × $20.00: $60.00
Total for this vial: $150.00

Vials & fees.

What ships, what's added at checkout

How many vials to send

Identity, Purity, Quantity share one vial.
Elemental Impurities (Heavy Metals) draws its own vial.
Bacterial Endotoxins, Sterility share one vial — sending it covers either or both.

Payment

Prices above are per sample. Card payments add Processing fee (2.7%) — processing fee, 2.7% of the order subtotal, computed once and shown before you pay.
