Dionex AS 40 Automated Sampler


-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.



Sample Delivery Method

Positive displacement against backpressure

 of up to 690 kPa (100 psi)


11 cassettes of either six 5-mL or eight 0.5-mL


Vial Size

0.5 or 5 mL

Filter Pore Size

20 micron

Minimum Volume Delivered

0.5 mL vials: 0.17 mL per injection

 5.0 mL vials: 1.7 mL per injection

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

 approximately 0.4 mL/min (0.5-mL vials) or

 1 mL/min (5-mL vials)

Injection Mode

Proportional: Delivers volume inversely propor-

 tional to the number of injections per vial

 Constant: Delivers fixed volume independent of

 the umber of injections per vial

Bleed Function

On: Displaces excess sample and any trapped air

 through bypass valve before sampling

 Off: Delivers sample and any trapped air directly

 to injection valve
