Three CETAC sample racks are available for the short configuration. These are
shown in Figure 3-12.
To assemble and place the samples and standards for a short configuration,
complete the following steps:
Ensure the short sample tray adapter plate is screwed into place in the center
of the rotary tray. It should be placed so that the alignment guide is placed
1
nearest the guide dot as shown in Figure 3-11. An ASX-112FR ordered in a
short configuration will be shipped with the adapter plate in place.
Place the standards vials in the rotary tray as shown in Figure 3-11.
2
Load the sample vials in the sample tray and place the tray in the center of the
rotary tray aligning the groove on the bottom of the tray with the alignment
3
guide on the adapter plate. This should also align the two alignment dots on
the corner of the sample tray and the rotary tray.
A correctly placed sample vial rack will not move more than ± 0.2 millimeters
unless lifted. A tilted sample vial rack or vials indicate an improperly placed
rack or vials, which must be corrected before you operate the autosampler.
Replace the autosampler cover by sliding it into the groove in the rinse
alignment block.

The cover on the ASX-112FR has a hinged front door, secured by a bar latch,
which can be opened to add or remove sample vials or the sample vial rack.
The entire cover itself can also be fully removed. Avoid removing the cover
during operation; this could result in an impact to the Y-arm assembly causing
an alignment error. In the case of a mechanically induced alignment error, the
power to the unit would need to be cycled off and on to realign the Y-arm.
