Introduction of the M.A.S.T.E.R. and S.O.S. Interactive Tools to Enhance the Reliability of Icp-oes Quantitative Results

These new interactive assistance tools, from Horiba Jobin Yvon, emphasize the use of multi-line analysis in an ICP-OES system. The aim is to enhance reliability in quantitative analysis. The tools are used with the recently introduced CCD-based ICP system, the ACTIVA, and they take into account possible changes in matrix concentration and unexpected spectral interferences.

These new tools are:

The M.A.S.T.E.R. (Multi-line Analysis Selection Tools for Enhanced Reliability) - Using a proprietary ICP-based spectra database containing not only wavelengths, but also limits of detection and line widths, the M.A.S.T.E.R. enables the user to easily perform multi-line selection with appropriate sensitivity and free of spectral interferences. The display of the selected analyte lines and their vicinity within the matrix
environment makes possible a final validation. Moreover, because the display tool can also include blank spectra, it may be used to select adequate background corrections. This tool, based on reconstituted spectra, basically reduces the need for the user to prepare various solutions and profile them.

The S.O.S. (Statistical Outlier Survey) - Once concentration measurements for each line have been obtained, an ANOVA-based statistical data processing tool is used to verify possible outliers providing a single reliable concentration result per element. With these two major tools, the ACTIVA is able to take full benefit of its CCD detector by offering interactive assistance to the operator through multi-line analysis yielding the most accurate quantitative analysis results possible.
