摘要: The present teachings provide methods for analyzing one or more amine-containing compounds in samples using isobaric labels and parent-daughter ion transition monitoring (PDITM). In various embodiments, the comprise steps of: (a) labeling with different tags from a set of tags, each tag comprising reporter portion; (b) combining at least portion isobarically labeled to produce combined sample; (c) subjecting sample PDITM; (d) measuring signal transmitted ions; (e) determining concentration based on comparison measured corresponding signals standard compound.
