During a bleed, the cap is pushed into the vial, starting from its topmost
position and stopping when it reaches the position at which the Dionex
AS-DV begins measuring the injection volume.
2.2.2 Rinsing Operating Principles
To deliver a rinse, the Dionex AS-DV performs the basic operation used
for delivering a sample. A vial containing the rinse liquid is moved to the
sampling head tower and the rinse liquid is delivered from the vial
through the sample out line. You can intermix sample vials and rinse vials
in any order in the carousel. The position of the rinse vial in the carousel
and the volume of rinse liquid to deliver is defined in Chromeleon.
You can also designate a range of vial positions to be reserved for rinse
vial use only. The rinse vial range is defined in the Chromeleon 7
Instrument Configuration Manager or the Chromeleon 6.8 Server
Configuration program (see
Section B.8.2 ). When performing a rinse, the
Dionex AS-DV takes the rinse liquid from the first vial in the range. If the
first vial is empty, the next vial in the range is used, and so on.
To define rinse cycles in Chromeleon, see Section 3.8.3 .
2.2.3 Optional High-Pressure Valve Operating Principles
A high-pressure valve can be installed in the Dionex AS-DV. Two models
are available: 6-port and 10-port. Both models are electrically-activated,
2-position valves. See the table below for valve kit part numbers.
Valve Kit Description Part Number
6-Port High-Pressure Valve Kit 068920
10-Port High-Pressure Valve Kit 068921
The Dionex AS-DV power must be turned off before you install or
rebuild a valve. If the power is on when you connect or disconnect the
valve cable, the Dionex AS-DV may be damaged.
