Mass spectrometry is an analytical technique used to measure the mass-to-charge ratio of ionized molecules. In peptide analysis, it helps laboratories confirm whether the expected peptide is present by comparing the observed mass with the theoretical mass from the sequence.
What it can show
- Identity confirmation by matching measured mass to the target peptide
- Impurity detection when unexpected mass signals are present
- Sequence-related information when tandem MS is used for fragment analysis
- Quality control support alongside HPLC and COA review
Results are typically interpreted together with chromatographic data, synthesis records, and the Certificate of Analysis (COA). This combined approach provides a more complete view of peptide quality than any single test alone. For laboratory research use only; not intended for human consumption.
