Analytical testing
Peptide analytical testing and quality documentation
Analytical documents answer different questions. HPLC describes a chromatographic purity result under a stated method; mass spectrometry supports an identity check; a batch record connects those results to supplied material. None alone proves every property a researcher may need.

HPLC vs LC-MS for Peptide Analysis
How chromatographic separation and mass-based identification answer different analytical questions.
Peptide Identity vs Purity: What Each Result Means
A practical distinction between a result that supports molecular identity and a result that describes chromatographic purity under a specific method.
How to Interpret a Peptide Chromatogram
A method-aware approach to retention time, peak integration, baseline separation, and why one chromatogram cannot answer every quality question.
What a Peptide COA Cannot Prove
The limits of a certificate: a reported result must be read alongside its batch, method, date, sample handling, and intended research question.
