1.1 Overview
The Dionex AS-HV Autosampler is a random access robotic device that can be
commanded to execute a series of liquid handling steps. The AS-HV can hold up
to 250 mL of sample and, through the use of a sample loading pump, deliver
sample to an ion chromatography (IC) system or other analyzer. Sample loading
pump options include a syringe pump, piston pump, or peristaltic pump (for
details, refer to
Section 2.4 ).
The AS-HV is designed to accommodate a variety of accessories, including a
sample rack, a standards rack, and a rinse reservoir. The standard configuration
for the AS-HV includes the following components:
•
A 24-position sample rack that accommodates 250 mL Nunclon sample flasks
•
An 11-position standards rack for loading of standards and/or samples
•
A PEEK
™
sampling needle for aspirating sample from sample containers
•
A sampling needle guide that prevents the PEEK sampling needle from
bending or flexing as it pierces a septum
•
A rack location mat that houses the sample rack and ensures alignment of the
sampling needle over each vial
•
A built-in rinse station (consisting of a peristaltic pump and a 150 mm
reservoir that circulates rinse fluid) that can be used to clean the sampling
needle between samples
•
A spill tray for secondary containment of samples
•
An RS-232 cable for communication with a PC (personal computer)
The AS-HV is usually controlled remotely from a PC running Microsoft®
Windows® XP or Windows® 2000 operating system and Dionex Chromeleon
®
Chromatography Management System software. The AS-HV communicates with
the PC via the RS-232 interface. Limited remote control is also available, using
relay signals.
