After the system has been switched from EI to CI mode, or vented for any other
C AU T I O N
reason, the MSD must be baked out for at least 2 hours before tuning.
Continuing with CI autotune if the MSD has an air leak or large amounts of
C AU T I O N
water will result in severe ion source contamination. If this happens, you need
to vent the MSD and clean the ion source.
