“…At the condition of CVG in this study, intensities of the Fe lines were too low for reliable measurements, although the formation of volatile Fe compounds in the reaction with NaBH 4 was indicated [41,42]. Unlike Sn and Hg that both easily form volatile species in the reaction with NaBH 4 , the signals derived from Mg at the CVG mode were observed due to the transport of a fine aerosol [17]. At PN and PN + CVG modes, the Mg II/Mg I ratio was 8.5-9.0 and 10-11 for 1000 W and 1200 W, respectively, showing that the plasma was in robust conditions.…”

“…The increase in during NaBH 4 hydrolysis with reference to the dry plasma and PN was about 50% and 40%, respectively [19]. In the other work [17], the values were above 70% higher at the CVG system than for dry plasma. Recently, spectroscopic and analytical characteristics of ICP with hydride generation with or without simultaneous introduction of the sample aerosol were presented by Pohl and Broekaert [11].…”

“…Excitation temperature is typically derived from atomic iron lines and the OH A-X 0-0 band serves usually for gas plasma temperature measurements. A number of papers have been devoted to ICP spectral diagnostics; however, nebulization systems have been predominantly investigated [6][7][8][9][14][15][16] in comparison to the reports concerning CVG [11,[17][18][19]. In the case of PN, the effect of hydrogen in addition to the argon or combined effect with a desolvation step was also discussed [19][20][21].…”

Electron density and ionization temperatures were measured for inductively coupled argon plasma at atmospheric pressure. Different sample introduction systems were investigated. Samples containing Sn, Hg, Mg, and Fe and acidified with hydrochloric or acetic acids were introduced into plasma in the form of aerosol, gaseous mixture produced in the reaction of these solutions with NaBH4 and the mixture of the aerosol and chemically generated gases. The electron densities measured from Hα, Hβ, Hγ, and Hδ lines on the base of Stark broadening were compared. The study of the H Balmer series line profiles showed that the ne values from Hγ and Hδ were well consistent with those obtained from Hβ which was considered as a common standard line for spectroscopic measurement of electron density. The ne values varied from 0.56·1015 to 1.32·1015 cm−3 and were the highest at loading mixture of chemically generated gases. The ionization temperatures of plasma, determined on the base of the Saha approach from ion-to-atom line intensity ratios, were lower for Sn and Hg (6500–7200 K) than those from Fe and Mg lines (7000–7800 K). The Sn II/Sn I and Hg II/Hg I, Fe II/Fe I, and Mg II/Mg I intensity ratios and the electron densities (ne) were dependent on experimental conditions of plasma generation. Experimental and theoretically calculated ionization degrees were compared.

“…A study of the effect of reagents commonly used in chemical vapour generation on ICP has shown that changes in plasma characteristics are due to H formation, rather than the presence of the reagents themselves (Welna and Zyrnicki 2009). Of several borane reducing agents tested, only NaBH 4 produced this effect.…”

This review describes developments major and in trace element determination using atomic absorption spectroscopy (AAS), inductively coupled plasma‐atomic emission spectrometry (ICP‐AES), instrumental neutron activation analysis (INAA), and X‐ray fluorescence (XRF) spectrometry that were reported in 2008 and 2009. Publication levels were comparable to those of previous years, except for XRF which showed an increase in the number of articles published in the past 2 years. In terms of number of publications and impact, the most active field was AAS, while INAA was the least active. As expected for well‐established and mature methods, novel developments for all four analytical techniques were relatively sparse. For AAS, the most notable publications concerned developments in sample introduction, particularly focussing on solid samples, increasing analyte sensitivity, and higher sample throughput. For ICP‐AES, publication of developments in sample introduction, remediation of matrix effects and calibration continues. Compared with past years, there was a clear focus on sample preconcentration methods, but very few publications reporting new hyphenated speciation methods. For INAA, there were several publications exploring the accuracy and robustness of the method, as well as the requirements for INAA to meet criteria for a primary method of measurement. Two other related techniques, delayed neutron activation analysis, and prompt gamma activation analysis, were also described. Hyphenated XRF techniques showed interesting developments in enabling XRF and XRD analysis on the same spot, and further work characterising and calibrating three‐dimensional micro‐XRF shows promising results for investigating sample heterogeneity.

“…14 In a number of papers, carbon-related matrix effect on plasma properties has been studied 15,16 including the effect of low-molecular-weight organic acids. [17][18][19][20] Also, the ethanol concentration inuence on plasma characteristics for Ar-MIP-OES coupled with CVG and a gas-liquid separator has been described by Włodarczyk andŻyrnicki. 21 They found that with ethanol concentration in the sample from 10 to 90% T rot increased from 2970 to 3820 K while T exc of Ar, H and Sb lowered in the ranges 5670-4800, 6190-3950 and 10 500-7390 K, respectively.…”
