Operation Controls
Enable ASXpress Operation
Enable ASXpress operation for normal operation.
Disable ASXpress operation if you want to test how the autosampler responds
to commands, as if the autosampler were connected directly to the host PC
without the ASX
PRESS PLUS system. (Note that a different tubing arrangement is
required to run the autosampler without the ASX
PRESS PLUS system.)
Extra Loop Rinse
Controls whether the probe and sample loop should take in air or rinse
solution between samples. The default setting (disabled, with a 1.0 second
purge delay) works well for most applications.
Enable Vacuum/Autosampler Peri-Pump Timeout
When this timeout is not enabled, the vacuum pump and autosampler
peristaltic pump will continue running indefinitely after sampling has stopped.
This introduces wear which can reduce the lifespan of the pumps. Enable the
timeout to specify a limit for how long the pumps should continue running.
Return Probe to Previous Sample
Controls whether the probe should automatically be returned to the position of
the previous sample, or remain at the rinse station. Depending on the method,
this selection can allow more efficient movement of the probe.
Manual Controls
Click the expand button to reveal the manual controls.
Valve Control
"Load" positions the ASXPRESS PLUS 6-port valve into the mode which loads the
sample loop, and illuminates the “Load” LED on the front panel of the ASX
PRESS
PLUS electronics module.
"Inject" positions the ASX
PRESS PLUS 6-port valve into the mode in which injects
the sample into the ICP (via the peristaltic pump on the ICP), and illuminates
the “Inject” LED.
These controls do not trigger any operation of the autosampler.
Vacuum Pump Control
Turns the vacuum pump in the ASXPRESS PLUS electronics module on and off.
