To Pump Down the MS

Ensure your MS meets all the conditions listed in the introduction to this chapter
WA R N I N G
before starting up and pumping down the MS. Failure to do so can result in personal
injury.
The use of hydrogen gas is specifically prohibited with this product.
WA R N I N G
Dangerous voltages exist inside the analyzer chamber, which can result in fatal
WA R N I N G
injury. Do not open the analyzer chamber door for any reason. If access is ever
required, trained service personnel must first disconnect the instrument from the
building power source.

Open the analyzer cover to access the analyzer quad driver board. See
Open the Analyzer Cover for Access to the Analyzer Sideplate"
Plug the power cord into a grounded electrical outlet.
Turn on the Q-TOF power switch
Press lightly on the metal box on the quad driver board to ensure a correct
seal.
The foreline pump will make a gurgling noise. This noise should stop
within a minute. If the noise continues, there is a large air leak in your
system, probably at the sideplate seal or the interface column nut.
Start the MassHunter Data Acquisition program. If the Q-TOF was
configured for both an EI and a CI ion source, you are prompted for the
ion source type that is currently installed. Click on an EI or CI ion source
type if prompted.
Select the MS Tune icon from the Instrument Control panel.
Select the Vacuum Control tab.
