Dionex AS40 Automated Sampler Ion Chromatography Autosampler
Web Information
The Dionex AS40 Autosampler is a low-cost, metal-free, rugged, automated, sample loading device designed especially for ion chromatography applications.
Key features provide performance and versatility:
- Simple front-panel layout makes the AS40 easy to learn and use.
- Metal-free flow path eliminates corrosion and metal contamination problems.
- Accommodates disposable PolyVial sample vials in both 5-mL and 0.5-mL sizes.
- Filter caps automatically filter the samples during delivery.
- Sample can be loaded to loops or concentrator columns.
- Bypass valve displaces excess sample or trapped air before sampling.
- Rinse vials can be placed anywhere in the sequence.
- The output relay function indicates if and when an autosampler load was completed.
- Automatic switching power supply for universal input voltage (90-265 V ac) simplifies instrument installation and setup.
