The Dionex Autoselect AS50 Autosampler precisely delivers from 1.0 to 99.9 µL (in 0.1 µL increments) or 100 to 1000 µL (in 1 µL increments) of sample to an injection valve.

Two types of trays are available for sample vials: one for 2 mL vials and one for 10 mL vials. During sampling, the tray remains stationary and a sampling needle arm moves from vial to vial. Up to 99 injections can be taken from each vial.

The AS50 can be controlled locally, from the front panel keypad and display, or remotely, from a Dionex workstation. The workstation consists of a computer with a Dionex DX-LAN Interface card and PeakNet software installed. Limited remote control is also available, using TTL and relay signals.

The AS50 can be configured with PEEK flow paths and components for ion chromatography (IC) applications, or with stainless steel flow paths and components for high-performance liquid chromatography applications (HPLC).

Control Panel

The control panel contains a liquid crystal display (LCD) and membrane keypad (See Section 2.2). The control panel permits manual control of all AS50 functions.

Autosampler Compartment

The autosampler compartment contains a stationary sample vial tray and a sampling needle arm that moves from vial to vial during operation (see Section 2.3).

Sample Temperature Control Option (Not Pictured)

The optional sample temperature control unit mounts under the autosampler and provides uniform heating and cooling of the vial tray. See Seetion 2.3.2 for details.

Syringe and Reservoir Organizer

The organizer an top of the autosampler Nolds the sample syringe, the flush liquid reservoir, the optional prep syringe, and the optional reagent reservoir(s). See Section 2.4 for details_

Chromatography Compartment Option

The optional chromatography compartment houses the components required for a single- or dual-column chromatography system. The components, such as the analytical column(s), cell(s), and suppressor(s), raust be ordered separately from the AS50. See Section 2.6 for details.

Thermal Compartment Option

A version of the chromatography compartment is available that provides heating and cooling of the chromatography components. See Section 2.6.2 for details.

Injection Valve

When the AS50 is configured without a chromatography or thermal compartment, the injection valve is installed in the autosampler compartment. When the AS50 is configured with one of the compartments, the injection valve is installed in the compartment. See Section 2.5 for details.
