Calibration failure on Synapt G2-S - WKB10448

Article number: 10448

SYMPTOMS

  • Automatic calibration fail and peak flags ('!') are seen on the acquired data in the calibration window.

ENVIRONMENT

  • Synapt G2
  • Synapt G2-S
  • Synapt G2-Si
  • Xevo G2
  • Xevo G2-S
  • Xevo G2-XS
  • MassLynx 4.1
  • MassLynx 4.2
  • UNIFI

CAUSE

Spectral resolution on the instrument is either too low or does not match that set in Acquisition settings.

FIX or WORKAROUND

  1. Check that Veff is set correctly
  2. Ensure that resolution and peak shape is suitably tuned for the Mode (Sensitivity, Resolution, or Hi Resolution) using Pusher Offset and Reflectron Grid parameters.
  3. Confirm that the Resolution field in the Acquisition Settings box is appropriate for the Mode, but also similar to the actual resolution displayed by the instrument.
  4. Rerun the calibration.
