Understanding the Fundamental Components of Sample Introduction for ICP-OES and ICP-MS.

Analytical techniques based on inductively coupled plasma (ICP) are commonly used for analyzing the elemental composition of a sample and are widely applied in analytical testing laboratories. Particularly for larger laboratories, analysis time and throughput are essential performance indicators, which can be severely impacted if sample analysis needs to be repeated because of insufficient stability or quality control (QC) failures. However, such failures are, in many cases, avoidable by selecting the right configuration of the sample introduction system of the instrument. This tutorial explains the most critical components of the sample introduction system of modern ICP-optical emission spectroscopy (OES) and ICP-mass spectrometry (MS) instruments, providing analysts with a guide for initial configuration settings and recommended maintenance intervals for reliable daily operation.
