The gases for the plasma torch are switched on and the gas lines are
purged. The plasma ignites and the interface rotary pump starts to
evacuate the interface vacuum chamber. When the change to Analysis mode
is completed, the title bar indicates that the instrument has changed from
Standby to Analysis mode.
CAUTION
Be sure to clamp the peripump tubing from the drain in the peripump. The drainage for
the spray chamber is provided by this peripump. If the spray chamber is not drained
properly, it will fill with solution causing solution to flow to the torch which will cause
the plasma to turn off.
NOTE
The Agilent 7500 returns to Standby mode when the plasma is off and remains there unless
the instrument is shutdown for major maintenance or for relocation.
