Install the Xpress Rinse Station and Modified Rinse
Tubing Arrangement
An Xpress rinse station and associated modified tubing arrangement is
required to accommodate the design requirements of the ASX
PRESS PLUS
system. Please note the following considerations:
Some ASX-1400 autosamplers come standard with the Xpress rinse station.
If you are connecting the ASX
PRESS PLUS system to an autosampler which
does not have an Xpress rinse station installed, then you will need to
replace it with the Xpress rinse station (supplied with the upgrade kit) and
make the tubing modifications, as described in this section.
The ports in the Xpress rinse station are smaller than the ones in the standard
rinse station provided with the autosampler. This smaller rinse station porting
allows the rinse solution to flow efficiently at the high flow rate used by the
ASX
PRESS PLUS system.
Figure 5-1 Xpress Rinse Station
The modified tubing arrangement provides for the injection of air bubbles
which will more rapidly flush the tubing between samples.
To retrofit the Xpress rinse station on an ASX-1400:
1 Verify that the autosampler is turned off and unplugged, and that no hazardous
materials are present in the rinse station or tubing.
2 Remove the screw to the right of the rinse station.
