Reading a Certificate of Analysis
- Purity (HPLC) — percentage of the target compound by high-performance liquid chromatography. We supply material tested to 98%+ purity.
- Identity (MS) — mass spectrometry confirms the observed molecular weight matches the theoretical weight of the target sequence.
- Lot / Batch number — matches the number printed on your vial label. A COA is only valid for the batch it names.
- Test date — the date the independent laboratory analyzed the batch.
