Abstract:

Since its introduction, ICP atomic emission spectrometry has increasingly attracted the interest of analysts and is widely used for routine elemental analysis. Some improvements in the analytical characteristics have recently appeared. These analytical characteristics can be described by using figures of merit that will reflect the quality of the analytical results,i.e. repeatability (precision) and accuracy, and of the instrument,i.e. number of elements that can be determined,selectivity (i.e. resolution),long-term stability, robustness (i.e. susceptibility to matrix effects), and limits of detection.
