Dionex AS-1 Autosampler

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