Ms/Ms Operating Modes - Waters Xevo TQ-S Operator's, Overview And Maintenance Manual

MS/MS operating modes

In SIR and MRM modes, neither quadrupole is scanned, so no spectrum
Note:
(intensity versus mass) is produced.
The following table shows the MS/MS operating modes.
MS/MS operating modes:

RADAR™ is an additional mode with which you collect data from the MRM
and full scan MS modes simultaneously. RADAR mode can also acquire all
detectable ions in both positive and negative full scan MS.
