“…Also, the ratio values showed in Figure 2 confirm the fact that radial viewing position is less sensitive to changes in matrix composition than axial. 26,31 Among the literature data of organic acid matrix effects in plasma, the monocarboxylic acetic acid is the most studied one. Several authors found the higher Mg ratio for acetic acid solutions.…”

“…11,24 By introducing the concept of robust plasma conditions when matrix composition changes do not significantly deteriorate analytical signal, a relatively simple experiment of measuring the Mg II / Mg I line intensity ratio as an indicator for robustness was proposed. 25 Some investigations of matrix effects involving Mg ratio measurements mainly describe the effects of easily ionized elements (EIE) on signal behaviour, 26,27 as well as the effects of inorganic acids as the most common matrices in plasma spectrometry analyses.

Abstract. In order to establish prerequisite conditions for hyphenation of inductively coupled plasmaatomic emission spectrometry with liquid chromatography, the effects on plasma signal by loading of low concentrated solutions of tartaric, citric and dipicolinic acid were studied. The intensities of Mn, Li, Mg, Cd and Cu lines were observed in axial and radial signal collection mode. Influences of different ligand concentrations on excitation conditions compared to water were evaluated on the basis of signal-tobackground ratio (SBR) and limits of detection (LOD). Lower LOD values were established in the solutions of tartaric and citric acid than in water solution. Higher values were observed in solutions of dipicolinic acid. The Mg II / Mg I line intensity ratio was calculated in order to compare the changes in excitation conditions. Polycarboxylic acid matrices showed slightly departures from equilibrium conditions (≈3 %) in radial observation mode. The effects of polycarboxylic acids monitored on ionic and atomic lines of Cd and Cu were of more complex nature which regards to the type of compound and concentration of the acid solution.(doi: 10.5562/cca2066)

Inductively coupled plasma atomic emission spectrometry (ICP/AES) and inductively coupled plasma mass spectrometry (ICP/MS) are well‐established techniques for elemental analysis. However, matrix effects can be considered to be their main pitfall. Changes in the performance of the system induced by the main sample component (or matrix) are referred to as matrix effects . As a result, the concentration obtained does not correspond to the actual one. Therefore, this is a problem that should be overcome. To do so, matrix effects must be understood. A full comprehension of the interferences begins with an evaluation of the contribution of each part of a spectrometer to the overall effect. This is only accomplished by means in‐depth fundamental studies. For more than 40 years, basic research has allowed to reach quite a high knowledge of the phenomena responsible for matrix effects. A representative sample of these is given in the present article. Some of the results of these investigations have allowed for the design and application of methods to find solutions that are appropriate for more or less general applications. In general terms, it may be stated that matrix effects have still not been fully mastered and more research is needed in this field in order to extend the field of applicability of ICP/AES and ICP/MS. Besides, the methods for overcoming interferences cannot be applied universally and new methods must be developed.
