MS/MS operating modes

The following table shows the MS/MS operating modes.

Product (daughter) ion mode

Product ion mode is the most commonly used MS/MS operating mode. An ion
of interest is selected for fragmentation in the collision cell, thus yielding
structural information.

Product ion mode:

Typical applications

•

Structural elucidation (for example, peptide sequencing)
