Shutting Down the Instrument

The Agilent 7500 is in Analysis mode during tuning and sample analysis. When not
being used for these procedures, the instrument remains in Standby mode. To
maintain or move the instrument, it should be placed in Shutdown mode and turned
off.
The following sections explain how to return the Agilent 7500 to Standby mode at
the end of each day and how to put the instrument in Shutdown mode when
necessary.

Putting the Instrument in Standby Mode

To return the instrument to Standby mode after running samples, complete the
following steps:
The Instrument Control window appears.
The dialog box appears.
The Instrument Diagram shows that the plasma is off. The Agilent 7500
automatically turns off all gases, the torch RF generator, the peripump, and the
cooling water flow, after cooling the torch and interfaces. Only the vacuum pumps
remain on.
Ensure that positive extraction remains operative while the instrument is in Standby
mode. The rotary pump exhaust continues to pass into the exhaust duct when the
instrument is in Standby mode.
