SYMPTOMS

  • Detector setup fails

ENVIRONMENT

  • SYNAPT G2-S
  • Xevo G2-S

CAUSE

Poor leucine enkephalin peak shape and intensity

FIX or WORKAROUND

  1. Tune the Xevo G2 QTof with leucine enkephalin for resolution and sensitivity, using Reflectron Grid, Pusher Off Set, Tube Lens, and Steering.
  2. Adjust Veff to move the observed leucine enkephalin mass to the correct position: positive ion 556.2771, negative ion 554.2615.

Detector Setup runs in Resolution mode. Even if Sensitivity mode is tuned well, Detector Setup may fail if Resolution mode is not performing optimally.
