If the pressure is high (above 5 × 10
system within the last 30 to 60 minutes, wait an additional 30 minutes and recheck the pressure.
If the pressure is decreasing with time, check the pressure periodically until it is within the typical
pressure range of the mass spectrometer.
If the pressure remains high, your system might have an air leak. If you suspect an air leak, shut
down the system as described in the topic
Make a visual inspection of the vacuum system and vacuum lines for leaks. Check each fitting and
flange on the system for tightness, and tighten the fittings or flanges that are loose. Do not tighten
fittings indiscriminately. Pay particular attention to fittings that have been changed recently or to
fittings that have been subjected to heating and cooling. Make sure that the cover plates of the
vacuum manifold are properly seated.

Things to Do After Operating the TSQ System

After operating the TSQ system, verify the instrument is ready for a period of inactivity by doing
the following:
• Flushing the Sample Transfer Line, Sample Tube, and API Probe
• Placing the System in Standby Condition
• Cleaning the Ion Sweep Cone and Ion Transfer Tube
• Emptying the Solvent Waste Bottle
