Mass spectroscopy using collision induced dissociation.

摘要

A method for using a QIT and for performing collisionally induced disassociation MS<n> experiments by scanning the trap potential sequentially so that the field first experiences a secular frequency of a selected parent ion and then the secular frequency of a CID produced daughter ion and then the secular frequency of a granddaughter ion and so on for each secular frequency of each progeny ion in descending mass order. <IMAGE>
