Overview

The Dionex AS Autosampler precisely delivers from 1 to 8,000

μ

L of sample to

an injection valve. The injection volume range delivered by a particular AS
depends on the size of the sample syringe and the sampling mode.

Modes

Several sampling modes are available:

•

In normal mode, sample is delivered to a single system and a sample loop is
installed on the injection valve.

•

In concentrate mode, the AS delivers sample to a Dionex ultra-low pressure
concentrator column.

•

In simultaneous mode, the AS can deliver sample to two independent ion
chromatography (IC) systems. Sample is delivered equally to the two IC
systems (50% of the volume to each). This mode requires the simultaneous
injection option.

•

In sequential mode, a diverter valve allows sample to be delivered to two
independent channels or IC systems through sequential injections. This mode
requires the sequential injection option.

•

In sequential concentrate mode, a diverter valve allows sample to be delivered
to two independent channels or IC systems on which Dionex ultra-low
pressure concentrator columns are installed.

Sample Temperature Control

The sample temperature control option provides uniform heating and cooling of
the vial tray.

Sample Preparation

The sample preparation option is used for automated dilutions and pipet functions.
