What MRM modes are available on SCIEX TripleQuad and QTRAP systems?

For research use only. Not for use in diagnostic procedures.

Answer

There are four different multiple reaction monitoring (MRM) modes that can be acquired using SCIEX TripleQuad or QTRAP systems with SCIEX OS software.

1) MRM: All transitions are monitored for every cycle throughout the entire method duration.

2) Scheduled MRM:  Transitions are only monitored within their defined retention time window during acquisition.

3) Scout triggered MRM RT mode: The marker transition and its dependent transitions are monitored for every cycle until the next marker transition exceeds its threshold.

4) Scout triggered MRM group mode: Transitions are monitored within their defined retention time window if the marker transition for the super group exceeds its threshold.



Scout triggered MRM is a new acquisition method type in SCIEX OS software version 3.1.6.
