Peak Area
Peak Area — The integrated area under a chromatographic peak, proportional to the amount of analyte and used for peptide purity and concentration calculations.
What Is Peak Area?
Peak area is the integrated area under a chromatographic peak, proportional to the amount of peptide producing that peak. Peak area is the basis for peptide purity calculation (% area), concentration determination (from calibration curve), and stability monitoring.
Usage
- Purity: % purity = (main peak area / total area) × 100. Reported on CoA
- Quantification: Compare sample peak area to standard curve of known concentrations
- Ratio: Analyte/IS peak area ratio corrects for injection variability in LC-MS
