摘要
A method of the analysis of compounds with mass spectrometry and to instruments, substances, and methods for polypeptide analysis, in particular in targeted proteomics applications and based on indexed retention times as peptide specific property. The method of chemical analysis comprises the steps of: a) providing a first sample comprising peptides; b) performing LC-MS and determining the empirical retention time values of the peptides; c) translating the empirical retention time values into the indexed retention time scale and associating a reference indexed retention time value; d) providing a second complex sample comprising peptides; e) performing LC-MS and determining the empirical retention time values; f) translating the empirical retention time values of the peptides into the indexed retention time scale by numerically adapting the transformation function; and g) determining the predicted empirical retention time value of the peptides by using the numerically adapted transformation function determined in step f).
