“…The complexity of organic matter impact is accomplished by entering solution into plasma where changes in excitation temperature and electronic density of plasma take place. Generally, organic matter present in solution can affect the emission which results with enhancement or suppression of signal [ 18 , 19 ]. Therefore, method of standard addition allows compensation of matrix effects which is also evident from the improved precision of measurements.…”

Tin content in samples of canned fruits and vegetables was determined by hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-OES), and it was compared with results obtained by standard method of flame atomic absorption spectrometry (AAS). Selected tin emission lines intensity was measured in prepared samples after addition of tartaric acid and followed by hydride generation with sodium borohydride solution. The most favorable line at 189.991 nm showed the best detection limit (1.9 μg L−1) and limit of quantification (6.4 μg kg−1). Good linearity and sensitivity were established from time resolved analysis and calibration tests. Analytical accuracy of 98–102% was obtained by recovery study of spiked samples. Method of standard addition was applied for tin determination in samples from fully protected tinplate. Tin presence at low-concentration range was successfully determined. It was shown that tenth times less concentrations of Sn were present in protected cans than in nonprotected or partially protected tinplate.

“…Above that level the excitation temperature decreases [111, 123,124]. For example, elevations of the excitation temperature up to 1000 K were reported in ethanolcontaining solutions at 15 % [123] and 30 % (v/v) with respect to aqueous media [124], while plasma excitation temperature decreases for higher organic contents.In another study at low RF power values (e.g., 0.75 kW),higher excitation temperatureshave been obtained with diluted acetic acid compared to water [122]. .…”

“…The obtained results suggested possible formation of smaller aerosol particles, and consequently greater amount of analyte in plasma. 22 However, there were no drastic discrepancies in measured LOD values; they comprised the same order of magnitude and showed that the measuring conditions were slightly different than in water.…”

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)
