Analysis
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
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
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 vial to public record
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.
Ship by USPS with your receipt and confirmation number enclosed. When the vials arrive we log them and assign an accession number.
Purity and identity are run from the same vial under the method above, and an analyst reviews the result before the certificate is released.
The signed certificate is emailed to you and filed to this public index, where your own customers can verify it independently.
Typical turnaround: 4–6 business days from when your vials arrive.
The public record
Certificates are public by default. A vendor can cite a batch; their customer can pull the same report from this page and read the chromatogram themselves.
Submit samples
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. Sample requirement is 2 mg minimum, shipped at ambient temperature unless the compound requires otherwise.
Email the Lab opens a new email to the lab. Attach your completed form before sending.
