2-8 Preparing the Mass Spectrometer for Operation
Purging the pump
Whenever you replace a solution bottle, purge the pump with the solution that
you are going to use next. See the mass spectrometer’s online Help for details.
Requirement:
Ensure that the end of the tubing is fully submerged in the
solvent in the wash reservoir.
Tip:
Depending on the solutions used, the system can require more than one
purge cycle to minimize carryover.
Rebooting the mass spectrometer
The reset button on the external EPC reboots the mass spectrometer.
Reboot the mass spectrometer when either of these conditions applies:
• The console software fails to initialize or connect.
• Immediately following a software upgrade.
Leaving the mass spectrometer ready for operation
When you are not using the instrument, stop the LC flow and put the
instrument in Standby mode, to conserve energy and reduce nitrogen
consumption.
Tip:
After you return the instrument to Operate mode, the LockSpray source’s
temperature requires as much as 30 minutes to stabilize at the relatively high
temperatures needed for UPLC operation.
