Analysis of Waste Water by ICP-OES with Twin Interface Plasma Observation

The multi-elemental analysis of waste water is one of the major applications for ICP-OES. This report demonstrates that the SPECTROGREEN TI has all the required analytical capabilities in terms of sensitivity, precision and accuracy to perform the analysis of waste waters. The SPECTROGREEN Twin Interface option enables the accurate determination of alkali and earth alkali elements without the need for ionization buffering by using the instrument’s radial mode. Trace elements are detected with high sensitivity using the axial mode. Instrument parameters and line selection are described. Low detection limits combined with a high analysis speed were achieved. Excellent results were found for spike recovery measurements in waste water.
