- The article describes the research on the impact of the type of system for introduction of samples into ICP plasma on selected parameters associated with the limit of detection. For this purpose, several sample introduction systems were chosen and tested by assessing the selected analytical parameters: Limit of Detection (LOD) and, additionally, Background Equivalent Concentration (BEC). The tests were carried out for 26 elements for which 48 spectral lines were selected. The sum of LOD and BEC values (determined for each line of a given element, for each of the sample introduction systems) were used for general comparison of the applied sample introduction systems. Based on the obtained results, the best sample introduction systems were selected for multi-element analysis, for which the lowest total LOD and BEC values were obtained. Graphs were also prepared showing the dependence of each of the LOD and BEC parameters on the spectral lines of selected elements. The analysis of the graphs allowed for grouping selected elements, based on the lines provided for measurements, in terms of the impact of the applied sample introduction system on LOD and BEC parameters, into three groups: element lines for which the weak influence of the used sample introduction system on LOD and BEC parameters is observed. This group includes the following element lines: Be 313.042, Cd 214.438, Cd 226.502, Mg 279.553, Mg 280.270, Mg 258.213, Mn 257.611, Mn 259.373, Sr 407.771 and Sr 421.552, element lines for which a moderate effects of the applied sample introduction system on LOD and BEC parameters are observed. This group includes the following element lines: Ag 328.068, As 189.04, As 193.759, Cu 324.754, Cu 327.396, Tl 190.090, V 292.402, V 292.464, V 311.071 and element lines for which the largest impact of the applied sample introduction system on LOD and BEC parameters is observed, this group includes the following element lines: K 766.491, Na 588.995, Na 589.592, Se 204.050, Sb 217.581, Ca 393.336. This information can be helpful when selecting the system for introduction of samples into the ICP OES spectrometer enabling the determination of a given element with the lowest detection limit.
