1 • Introduction to the Dionex AS-DV
1.1 Overview of the Dionex AS-DV
The Thermo Scientific Dionex
™
AS-DV Autosampler is a compact autosampler
that is capable of delivering between 0.1 mL and 5.0 mL of sample (in 0.1 mL
increments) to the sample loop or concentrator column in an ion chromatography
(IC) system. The Dionex AS-DV is compatible with the Thermo Scientific
Dionex ICS-5000, ICS-2100, ICS-1600, ICS-1100, and ICS-900 systems, as well
as legacy IC systems.
The Dionex AS-DV holds 50 vials (either 0.5 mL or 5.0 mL, or a combination of
the two sizes). Vials can be sampled in any order and multiple samples can be
taken from each vial. The autosampler remembers the vial size and volume
delivered for each vial position, allowing multiple samples to be taken from a vial
non-sequentially.
The unique Thermo Scientific Dionex PolyVial
™
sample vial incorporates a cap
that acts as a simple piston to force sample out of the vial. This eliminates the
need for an external sampling pump. Sample can be delivered to a sample loop or
a concentrator column with backpressures up to 690 kPa (100 psi). Caps with a
20
P
m filter are available to remove solid materials from the sample before
injection.
The Dionex AS-DV can be configured either without a valve (the standard
configuration) or with an optional 6-port high-pressure valve or 10-port high
pressure valve.
The Dionex AS-DV is controlled with a PC configured with Thermo Scientific
Dionex Chromeleon
®
7 Chromatography Data System (release 7.0 or later) or
Chromeleon 6.8 Chromatography Data System (release 6.80 SR6a or later). The
autosampler connects to the Chromeleon PC with a USB cable.
The Dionex AS-DVcan also be operated under relay control from a device
capable of executing timed events, such as a previous generation IC system
without USB connectivity.
