5.2.3 MS The MS menu item is only available when a PurIon Mass
Spectrometer is added to the ACCQPrep system. The following
options are available:
Method Development – Choose this command to open the

ETHOD EVELOPMENT
conditions for the compounds to be purified. This command
is not available from a remotely connected computer via a
web browser.
Ion Finder – Enables you to find fragments and adducts
based on the molecular weight of their desired compound.

fragments based on the value entered in the desired
mass control and detected by the system. Checking
one of these values adds it to the D
Manual Control – Use this command to open the MS
M C window to prime and control the carrier

solvent pump and switching valve on the mass
spectrometer fluid interface. This command is not available
from a remotely connected computer via a web browser.
Ionization settings – This command opens the I
S window to allow creation of custom ionization
ETTINGS
parameters that can be saved for various compound classes
and projects. This command is not available from a
remotely connected computer via a web browser.
Operate – This command sets the status of the PurIon mass
spectrometer from standby to an operational mode by
applying power to the heaters and dynode detector. The
nitrogen gas is also supplied to the nebulizer. If the mass
spectrometer is already in operate mode, the S
button will display.
Standby – This command is available when the PurIon is in
the O mode. It turns off all high voltages within the
PERATE
PurIon including the dynode detector which prolongs its
life. In addition, it sets the inlet capillary heater
temperature to 50 °C and the remaining heaters off and
lowers the gas flow rate to ~.2 liters/minute. When in
standby mode, the operate command is used to return the
PurIon to the operational state (high voltages on, heaters
on, and gas flow at the proper rate of ~4 liters/min).
Shutdown – This command removes power to the heaters,
and removes power from the turbomolecular pump. A
window will appear confirming that you want to initiate the
shutdown procedure. This command is used to shut down
the PurIon mass spectrometer for maintenance or to move
the system.
