Documentation & quality
Every lot, documented.
We supply analytical documentation for the specific lot you receive — not a generic sheet. Identity, purity, and mass confirmation, tied to a batch number, available on request before or after you order.
Purity — HPLC
High-performance liquid chromatography quantifies purity as a percentage of total peak area and flags related impurities.
Identity — Mass spec
Mass spectrometry confirms the measured molecular weight matches the expected mass for the sequence.
Traceability — by lot
Each vial carries a batch number. The COA and supporting data you receive correspond to that exact lot.
What a Certificate of Analysis shows
A COA is the summary record for a batch. For our research peptides it typically reports:
- Product & sequence — compound name and amino-acid sequence
- Batch / lot number — the identifier printed on the vial
- Purity (HPLC) — percentage by peak area, with method conditions
- Identity (MS) — observed vs. theoretical molecular weight
- Appearance & net content — physical form and fill
- Analysis date
