Tune is interrupted.
Cannot find calibration gas peaks.
Cannot perform detector gain calibration.
Cannot calibrate resolution.
Cannot perform mass calibration.
An air leak has been detected.
Table 33.
Possible Remedy if Tune is Interrupted
Make sure the computer is not set to go into Standby mode while you are acquiring data for your tune. Otherwise, it may interrupt your
tune.
Table 34.
Possible Remedies if Calibration Gas Peaks cannot be Found
Run an initial tune.
Check the calibrant reservoir and add 50 μL (max) of FC 43, if necessary. See
Maintaining the Calibration Gas Module
Make sure the ion volume and lenses are properly installed and clean.
Make sure the stainless steel tubing inside the manifold is connected to the mixing chamber.
Table 35.
Possible Remedies if cannot Perform Detector Gain Calibration
Make sure you have an ion signal. The gain tune uses ions, so the system must have a signal to start.
Replace the electron multiplier if the voltage required to generate 3 x 10
5
gain on your electron multiplier is >2200 V. See
Components of the Electron Multiplier
for details.
Replace the electrometer board. See
for details.
Table 36.
Possible Remedies if Resolution cannot be Calibrated
Allow contaminants to pump away so they do not interfere with
m/z
100 or
m/z
502.
Run a full automatic tune if calibration gas ions (
m/z
69, 131, 264) are present, but more than ±12.5% or ±20 u off (whichever is smaller).
Table 37.
Possible Remedies if Mass Calibrations is not Performed
Allow contaminants to pump away so they do not interfere with calibration gas ions.
Calibrate by running an automatic tune.
Table 38.
Possible Remedy for Air Leaks
Check the system for air leaks and address them.
