Product (daughter) ion mode

Product ion mode is the most commonly used MS/MS operating mode. You can
specify an ion of interest for fragmentation in the collision cell, thus yielding
structural information.
Product ion mode:
Typical applications
You typically use product ion mode 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 (for example, peptide sequencing).
