N2 - Plasma pencil is a capacitively coupled discharge (CCP), which is tested as an alternative excitation source for determination of elements concentrations in solutions [1, 2]. The discharge can excite elements of 1st and 2nd group of the periodic table and also some other metals of which melting and boiling temperatures are not high related to the pencil plasma temperature. Among them mainly copper and zinc emissions were already studied under various conditions. It was shown that intensities of their atomic lines are suppressed by the presence of easily ionisable elements (EIE: 1st and 2nd group of the periodic table) in the sample solution [3]. The suppression was also found in the presence of nitric acid. Significant differences were also found for different anions in combination with sodium cation in the solution. It seems that the most intensive depression effect is caused by chlorides, less effect is observed for nitrates and sulphates and the dependence on the sulphate concentration is not monotonous. To find out if a plasma pencil can be used as an alternative excitation source, we have analyzed real drinking water samples by plasma pencil and ICP-OES and we can say that the yielded results do not differ significantly.
