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.
Specifications
| Sample delivery method | Positive displacement against backpressures of up to 690 kPa (100 psi) |
| Capacity | 11 cassettes of either six 5-mL or eight 0.5-mL PolyVials |
| Vial size | 0.5 mL or 5 mL |
| Filter pore size | 20 µm |
| Minimum volume delivered | 0.5-mL vials: 0.17 mL per injection
5.0-mL vials: 1.7 mL per injection |
| External control | Input: Load
Output: Ready |
| Injections per vial | 1, 2, or 3 |
| Injection type | Loop: Delivers sample rapidly to sample loop (~4 mL/min)
Concentrator: Delivers sample against backpressure of up to 690 kPa (100 psi) at ~0.4 mL/min (0.5-mL vials) or 1 mL/min (5-mL vials) |
| Injection mode | Proportional: Delivers volume inversely proportional to the number of injections per vial
Constant: Delivers fixed volume independent of the number of injections per vial |
| Bleed function feature | On: Displaces excess sample and any trapped air through bypass valve before sampling
Off: Delivers sample and any trapped air directly to injection valve |
| Power supply | Automatic switching power supply for universal input voltage (90–265 V ac), (47–63 Hz). |
