Analysis

Two measurements on every certificate.

A purity figure with no identity confirmation answers half the question: it says the sample is clean, not that it is the compound on the label. We never issue one without the other.

Measurement 01

HPLC-UV — purity

Reversed-phase separation with ultraviolet detection at 214 nm, the wavelength at which the peptide bond absorbs. Purity is reported as area percent of the total integrated signal, to two decimal places.

Measurement 02

LC-MS — identity

Electrospray ionisation in positive mode. The observed mass-to-charge ratio is matched against the theoretical mass of the named sequence, including the multiply charged states expected from larger peptides.

From form to public record

Four steps, one of which is out of our hands.

01

Submit & pay

Email your submission form with Email the Lab. If it is accepted you receive a payment link, and once paid, a confirmation number and receipt. Declined submissions are notified by email.

02

Ship your vials

Ship by USPS with your receipt and confirmation number enclosed. When the vials arrive we log them and assign an accession number.

03

Analysis & review

Purity and identity are run from the same vial under the method above, and an analyst reviews the result before the certificate is released.

04

Report issued

The signed certificate is emailed to you and filed to this public registry, where your own customers can verify it independently.

Typical turnaround: 4–6 business days from when your vials arrive.

Send a vial. Get a certificate your customers can check.

Download the submission form, complete it, and send it to us with the Email the Lab button. All submission forms must be submitted by email. If your submission is accepted, you'll receive a payment link at the email address on your form; if it's declined, we'll let you know by email. Once payment is complete you'll receive a confirmation number and receipt: include both with your vials when you ship.

Email the Lab opens a new email to the lab. Attach your completed form before sending.
