1. Test

IdentityLC–MS (ESI+). Confirms that the main component has the exact mass of the named peptide: every charge state we record within 10 ppm of the formula. A mass match cannot tell a D- from an L-amino acid; we do not sequence. $95 PurityRP-HPLC–UV at 214 nm, area percent, with the chromatogram. $145 Identity + PurityIdentity and purity on one sample, one report. $185 Full panelIdentity + Purity with Mass per vial, Water content and Bacterial endotoxin. $340

2. Add-ons

Mass per vialExternal-standard HPLC against a named reference standard. Reported as mg of free peptide per vial, with the salt and water accounted for. Adds to Identity + Purity only, because it rides on the same HPLC run and reference standard. +$60 Water contentCoulometric Karl Fischer, whole vial. Reported as mass percent. Adds to Identity, Purity or Identity + Purity; the Full panel already includes it. +$55 Bacterial endotoxinKinetic chromogenic LAL. Reported in EU per mg of powder; no limit is applied unless you supply one. Adds to Identity, Purity or Identity + Purity; the Full panel already includes it. +$95

Run on the same sample. All three add-ons on Identity + Purity is the Full panel, the same five tests; we charge the Full panel price.

3. The sample

Peptide (required)

Number of samples (one lot per sample; one accession and one report each. Above our weekly capacity, tell us before you ship)

Your lot or batch reference (printed on the report so a buyer can match it to the vial)

Label claim, if any (printed beside the result)

Special handling (optional)

4. Where to send the report

Email for the report and the invoice (required)

I may lawfully possess and ship this material, and I accept the terms: the report is published under its number whatever it says, no sender’s name is recorded, and results are as measured. (required)

Read the terms; they are short.

How a conclusion is reached

Where you supply a specification or the vial carries a label claim, the conclusion on the certificate follows the rule stated in the terms and printed on every certificate. Decision rule (ISO/IEC 17025:2017 7.8.6; ILAC-G8:09/2019): the conclusion is reached by simple acceptance (guard band w = 0) on the value rounded to its reported precision; the statement beside it says whether the conclusion still holds with the expanded uncertainty (k = 2) included, the guard band w = U.

Orders go by email; there is no online payment. This composes an email to help@cupel.ca with your order filled in. We reply within one business day with your invoice, payable on receipt. Your order reference is ; it is in the subject line, keep it.

How much to send

Identity (ID) — one sealed vial as sold
Purity (PUR) or both (IDP) — one sealed vial as sold
Mass per vial (QNT) — three sealed vials as sold
Water content (H2O) — two sealed vials as sold
Bacterial endotoxin (LAL) — one sealed vial as sold
Full panel (FULL) — five sealed vials of the same lot, as sold: three are dissolved whole, by mass, to 2.0 mg/mL nominal in LAL reagent water (10 mM Tris of LAL grade for semaglutide, tirzepatide and retatrutide), for content per vial; purity, identity and endotoxin are taken from those solutions. Two more are used whole for water content.

Vials received beyond the requirement are retained unopened for 30 days after the report issues.

How to pack it is on the sending page.

Packing

Send the sealed container exactly as you received it: do not decant, reconstitute or relabel it. One lot per accession. Room temperature is fine for a lyophilised powder in transit; if yours needs cold chain, say so in the email and we will tell you how we receive it.

Paying

We email the invoice as soon as your testing request is submitted, payable on receipt; testing starts when your sample is logged, and a missed turnaround refunds the payment.

Payment details come with the invoice, which we email when you submit your request.

Volume and the clock

The 10-day guarantee applies per accession up to our weekly capacity. Above that, tell us before you ship and we give you a date in writing; that date, not 10 days, is then the one we are held to. A box above capacity sent without warning is received, logged and dated honestly, and the guarantee does not apply to it. Sending a box of many samples? Tell us before you ship and we schedule them.
