7.1 Introduction in LC-Ms/Ms-based discovery studies, many thousands of peptides can be determined from complex samples, most appearing as multiple signal features due to differing numbers of protonation. raw analytical data are significantly complex, on the order of gigabytes, with many thousands of Ms1 spectra collected across a single liquid chromatogram. each mass spectrum contains 100–1000s of unique features, with each feature being separated across multiple mass spectra. the first aim of Ms1 quantitation is to directly estimate the intensity of each feature by integrating the ion count under its chromatographic peak shape or extracted ion chromatogram (xiC). assuming detector linearity, this intensity is proportional to the ion count, which is proportional to peptide abundance. since ionisation efficiency varies between features, only relative abundance changes across treatment groups can be established, by inferring ratios of how abundance differs between those samples. nevertheless, some level of absolute quantification is possible if we possess
