Abstract
Methods and systems for separating and/or quantifying peptides using differential mobility spectrometry (DMS) are provided herein. In accordance with various aspects of the applicant's teachings, the methods and systems can provide for the separation of one or more peptides, for example, peptides that may be difficult to separate with conventional techniques, such as mass spectrometry (MS), by complexing the peptides with a metal cation (e.g., Ca2+) prior to DMS. In some aspects, the present teachings can prevent proton stripping from ionized peptides that can occur in DMS to prevent unintended and/or undesirable alterations to the peptide's charge state distribution.
