Make sure your MS meets all the conditions listed in the
introduction to this chapter 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.
Dangerous voltages exist inside the analyzer chamber, which can
result in fatal 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.
P
rocedure
1 Open the analyzer cover to access the analyzer quad driver
board. See "To Open the Analyzer Cover for Access to the
Analyzer Sideplate"
2 Plug the power cord into a grounded electrical outlet.
3 Turn on the Q-TOF power switch
4 Press lightly on the metal box on the quad driver board to
ensure a correct seal.
Do not push on the filament board safety cover while pressing on the
analyzer board. This cover was not designed to withstand this type of
pressure.
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.
5 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.
