Abstract

Deficiencies with the current European reference method for the analysis using inductively couple plasma-mass spectrometry of metals in emissions samples from stationary sources based on experimental data obtained from real samples are presented. The effect of these deficiencies on the quality and accuracy of data is highlighted with errors of up to 40 % being observed in real samples. Suggestions to improve the performance of the standard method are presented. In particular, the beneficial effect of using a drift correction procedure to take account of the decrease in instrument sensitivity observed during an analytical measurement series is demonstrated. It is shown that this corrective procedure results in substantial improvements to the accuracy of data produced.
