ICP-OES Measurement

Overview

This section introduces sample measurement procedures, with part 15 covering procedures for ICP-OES and later parts covering measurement for ICP-MS. This section is for advanced chemists who are already familiar with using the instrumentation. Most of the information and tips I supply here will not be found in a standard textbook; rather they reflect the major considerations of sample measurement based on my own personal experience.

When developing an ICP-OES measurement procedure, the following concerns should be addressed:

1. Line selection
   •   Sensitivity requirements
   •   Precision requirements
   •   Spectral interferences and background correction
2. Matrix effects
3. Method validation (to be addressed later in a later part of this section)
