AbstractAbstract
[en] In this work a radiofrequency capacitively coupled plasma at atmospheric pressure as spectral source for analysis of liquid and solid samples is presented. This discharge is in contact with only one electrode. The plasma support gas is Ar with a flow-rate of 0.6 - 2 l.min-1. The frequency of the electromagnetic field is 27.12 MHz and the adsorbed power into the plasma is 85 - 275 W. Detector are in the range of 10-6 - 10-9 g.ml-1 for mono-and multielement liquid samples analysis and detection sensitivity are lower than 1% for solid samples (brass and low-alloy steel) analysis. The dependence of emission line intensities on various parameters has also been studied. (Author)
