Warwick Analytical Service (WAS), the analytical division of Exeter Analytical, has developed an inductively coupled plasma - optical emission spectrometry (ICP-OES) methodology.
The new ICP-OES methodology enables the WAS to screen samples for up to 70 elements.
Developed to provide a rapid semi-quantitative screen of 70 elements from beryllium to uranium, the automated ICP-OES methodology compares measured intensities to the intensities of traceable standards to obtain the elemental concentrations in the unknown sample.
Multiple analytical wavelengths are used to avoid spectral interferences.
Using solid or liquid samples (less than 500mg), the WAS screening methodology is able to provide rapid elemental detection down to 1ppm.
For materials such as metal oxides, metallic catalysts, polymers and geochemical materials that do not dissolve well by traditional means, high-pressure microwave digestion apparatus is used to effectively and rapidly digest samples ready for ICP-OES analysis.
Experimental data is reprocessed to improve the quality of results.
