1 Introduction
Overview
The CETAC Technologies ASXPRESS
®
PLUS Rapid Sample Introduction System is
designed to increase autosampler throughput by reducing the sample delivery,
stabilization, and washout time (See Figure 1-1 and Figure 1-2 for cycle
diagrams). The CETAC ASX
PRESS PLUS uses a combination of a metal-free 6-port
injection valve with an inert high-speed vacuum pump to enable rapid sample
loading and probe wash out.
The ASX
PRESS PLUS system is comprised of two main components: an
electronics module and a valve/pump module. The separate electronics and
valve/pump modules provide the smallest possible injection valve size to allow
the valve to be placed close to the instrument’s nebulizer.
The complete ASX
PRESS PLUS system is comprised of these main components:
The ASXpress valve/pump module
The ASXpress Plus electronics module
An external rinse pump
A power supply
An autosampler
Windows-based software to configure and coordinate the system
The ASX
PRESS PLUS electronics module executes a macro automatically when
the probe is placed into the sample. The macro ends when the probe is lifted
out of the rinse station.
