Abstract
A method () for analyzing chemicals includes fractionating a complex sample into at least two sample portions that each includes potions of two polypeptides though in different concentration ratios, digesting and performing LC/MS on each of the sample portions (, and associating precursor ions observed via LC/MS with their corresponding polypeptide in response to LC/MS provided intensity data (). A set of precursor ions that has substantially similar intensity ratios in both sample portions is determined to be associated with the same polypeptide.
