Course Description
Recently ICP-AES instrumentation has undergone tremendous progressive changes. New instrumental and plasma observation configurations have been developed resulting in considerable improvements in analytical performance. This sudden evolution has taken place due to the recognition by users and manufacturers, that detection limits can be significantly enhanced and easily ionized element effects on analyte intensities can be considerably reduced by optimizing plasma operating conditions and observation configurations. Otherwise prevalent interference effects result in matrix mismatches between calibration standards and samples and erroneous analytical results. This awareness occurred due to benchmark fundamental investigations on plasma robustness, observation configurations (axial vs. radial) and cross-over points in the plasma column by Houk, Mermet, Hieftje and others. These investigations included vertical and radial variation of electron number densities, electron and gas-kinetic temperatures, spatial distributions of atom and ion intensities and possible energy transfer from the toroidal region to the central channel of the plasma – to mention just a few. In this short course we will endeavor to describe the analytical merits of these new instrumental and plasma observation developments by providing experimental data using the various configurations.

Target Audience
This course is intended for all laboratory personnel - operators, managers, quality control and assurance specialists, research scientists, environmental chemists, geochemists, biologists, metallurgists, toxicologists, new and experienced users of atomic absorption and plasma spectrometry, and technical personnel at all levels.

Course Outline
1. Overview of recent instrumental developments including Microwave Induced Plasmas (MIP).
2. Advantages of low UV wavelength range for determination of halogens and other elements.
3. New developments in axially, radially dual and simultaneous “Multiview” viewed plasmas.
4. Comparison of the configurations using conventional figures of merit (limits of detection, response linearity, and EIE induced matrix effects).
5. Evaluation of plasma observation and configuration i.e., methods of cool plasma cut off.
6. Effect of ICP operating conditions (RF power, nebulizer flow rate, and torch configuration) on robustness (Mg II 280/Mg I 265 ion-to-atom intensity ratios).
7. Robust operating conditions as expressed by minimum effect of Na and Ca on ion and atom line intensities.
8. Cross-over point. Vertical intensity variations of analyte ion and atom lines and regions of minimum interference due to easily ionized elements.
9. Optimization of ICP operating conditions – determination of robust conditions and the cross over point
10. Effect of methanol on high ionization potential elements
