Abstract
The present disclosure relates to a method for using chemical tags which have two or more sites for ionization to improve quantification and identification of components of interest from a complex mixture. This method relies on first selectively reacting one or more component in a sample with a chemical tag having two or more sites for ionization, followed by separation of components based on charge status, and finally characterization of each component to identify the same. Additionally disclosed are compounds useful as chemical tags in the disclosed methods.
