LED Display
Four LEDs on the Dionex AS-DV front panel (see Figure 2-2 ) indicate
the status of the following autosampler functions.
Other status information and alarm messages are displayed in the audit
trail in Chromeleon. For a description of these messages, see
Section 4.1 .
Sampling Mechanism
The sampling mechanism consists of a sampling head tower, a vial
carousel, and a carousel cover (see
Figure 2-1 ).
•
The sampling head tower delivers sample from the sample vials to the
sample out line, which exits the front of the Dionex AS-DV (see
Section 2.1.2 ). For a description of how the sampling mechanism
operates, see Section 2.2.1 .
•
The carousel holds the PolyVials containing sample or rinse solution.
Vial numbers are molded into the top of the carousel to indicate the
sampling position. Vials can be placed in any order in the carousel.
The Chromeleon sequence controls the order in which sampling
occurs. For a description of how to create a sequence, see
Section 3.6 .
Sensors in the sampling mechanism detect the presence (and the size)
of the vial under the sampling head tower.
