Peptide purity documentation should provide more than a single percentage. A useful documentation package should help a laboratory evaluate peptide identity, chromatographic purity, batch traceability and the limitations of the analytical methods used. High-performance liquid chromatography and mass spectrometry provide different types of evidence. HPLC can describe the chromatographic profile of a sample under defined […]

Batch-level testing for research chemicals connects analytical results to a specific production or testing lot. Rather than relying on a general report for a compound name, researchers can use a batch number to determine whether a Certificate of Analysis corresponds to the material being evaluated. This distinction matters because separate batches of the same compound […]

Understanding HPLC vs mass spectrometry for research compounds helps researchers distinguish between chromatographic purity information and molecular identity evidence. Although both methods appear frequently on Certificates of Analysis, they measure different properties and should not be treated as interchangeable tests. High-performance liquid chromatography, or HPLC, separates detectable components within a sample. Mass spectrometry, or MS, […]

Learning how to read a research compound COA is essential when reviewing the identity, purity and batch documentation of a laboratory material. A Certificate of Analysis should connect a specific batch to clearly reported analytical results rather than simply display a purity percentage. HPLC, mass spectrometry and NMR provide different kinds of information. No single […]
