Introduction
The Assist™ automated sample introduction system has greatly enhanced the
performance of ICP-OES and ICP-MS instruments. The Assist combines Flow Injection
technology with purpose-built programmable syringe drives to reduce the typical analysis
time by more than 50%. This combination provides the highest level of accuracy, stability
and sample throughput by controlling the delivery of both sample and internal standard
or diluent. It eliminates the inaccuracies and pulsations caused by peristaltic pumps, as
shown in Figure 1. In this report we will present the benefits of the Assist and introduce
three different configurations: the Basic Package, Premium Package, and Oils Package;
to show how the Assist can tackle most ICP-OES and ICP-MS applications.
