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. They are 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 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

Measures bacterial endotoxin by the fluorometric LAL test (USP ⟨85⟩), down to 0.03 EU/mL.
LAL (fluorometric)
Price$110.00Turnaround5 business days
Bacterial Endotoxins is temporarily not available — listed for reference, not orderable.
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.

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.

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. Each analyte is reported on the same certificate with its own identity and percent of its own labeled amount, with one purity for the whole vial. That percent is measured against the concentration you state for that analyte, which is why the order form asks for each analyte's concentration.

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 a 2.7% processing fee on the order subtotal, shown before you pay.
