Default panel is HPLC + LC-MS — chromatographic purity plus intact-mass identity support. Account-linked CoAs, public verify by report code, and a trade path for volume sellers. Research characterisation of materials you submit — not clinical grade, not for human use.
Purity + identity
Intro: £300 for your first 5 samples (signed-in account), then £349 list.
£349 per sample for HPLC + LC-MS after intro. Same panel, same turnaround aim.
Purity — how clean the main peak looks under HPLC.
Identity — whether the mass is consistent with the named peptide.
Available on request · £249. Purity alone does not confirm identity. Most sellers should start with HPLC + LC-MS.
One sample · one peptide · dual result panels. No ISO/UKAS accreditation claims on this site.
Chromatographic main-peak area % under HPLC-UV/PDA. Shows relative purity of the submitted material — not net content or potency.
Intact-mass identity support. Report wording: “Consistent with {peptide}” when mass aligns with the named compound on the job.
