Waters Xevo TQ-S cronos - Product (Daughter) Ion Spectrum; Precursor (Parent) Ion Spectrum

1.7.1 Product (daughter) ion spectrum
Product ion spectrum is the most commonly used MS/MS operating mode. You can specify an
ion of interest for fragmentation in the collision cell, yielding structural information.

1.7.1.1 Typical applications
You typically use product ion spectrum for the following applications:
• Method development for MRM screening studies:
• Identifying product ions for use in MRM transitions.
• Optimizing CID tuning conditions to maximize the yield of a specific product ion to be used
in MRM analysis.
• Structural elucidation.
