Scanwave Daughter Scan Mode; Leak Sensors - Waters Xevo TQ-S Operator's, Overview And Maintenance Manual

1 Waters Xevo TQ-S Overview

ScanWave daughter scan mode

This operating mode is very similar to the conventional product ion mode in
that you can specify an ion of interest for fragmentation in the collision cell,
thus yielding structural information. Nevertheless, in this ScanWave mode,
the cell accumulates ions (intact or fragments) and then releases them,
according to their mass, in synchrony with the second quadrupole mass
analyzer. This mode results in a significant increase in the signal intensity of
full scan spectra.

Leak sensors

Leak sensors in the drip trays of the Xevo TQ-S continuously monitor the
instrument for leaks. A leak sensor stops system flow when its optical sensor
detects approximately 1.5 mL of accumulated, leaked liquid in its surrounding
reservoir. At the same time, the Instrument Console or UNIFI software
displays an error message alerting you that there is a leak.
