“…OES (i.e., slurry sampling -chemical vapor generation -pneumatic nebulizationmicrowave induced plasma optical emission spectrometry) for As, Bi, Ge, Sb, Se, Sn, Hg, Ca, Fe, Mg, Mn, and Zn determination [20,21]. These same authors also evaluated the performance of a commercial, specially designed continuous-microflow ultrasonic nebulizer dual capillary system for determination of volatile species by MIP OES [20,21]. Asfaw and Wibetoe [22] developed a procedure for the simultaneously analysis of hydride and non-hydride-forming species using the commercial multimode sample introduction system ® (MSIS) by ICP OES.…”

A new Flow Blurring ® multiple nebulizer (FBMN) has been used for the efficient generation of As and Se hydrides directly into the aerosol formed inside the spray chamber before detection by inductively coupled plasma optical emission spectrometry (ICP OES). The FBMN allowed the hydrides generation directly into the spray chamber without using any additional device either for solution and gases control or for gas phase separation. Synthetic solutions containing As and Se plus Ca, Mg and K were used for evaluating matrix effects and Ge was suggested as internal standard. Limits of detection of 2.7 and 5.8 µg L-1 were obtained for As and Se, respectively, when keeping the nebulization gas flow rate at 0.60 L min-1 and the liquid flow rate at 0.67 mL min-1. The developed procedure was applied for spiked digests of food samples and quantitative recoveries were attained. The combination of FBMN, internal standard and hydride generation is a robust and simple approach for generating As and Se hydrides directly into the aerosol.

“…In the CVG system used in the present study, unlike in other systems, [9][10][11][12] only one gas supply was used to carry volatile hydrides of As and Sb in addition to cold vapors of Hg and to sustain the plasma. The CVG reaction was initiated by mixing an acidified HCl sample solution with an alkaline THB solution in a perfluoroalkoxy (PFA) Y-shaped connector.…”

Spectroscopic and analytical characteristics of a low power atmospheric pressure mixed argon-helium microwave induced plasma were examined for its usefulness in the determination of As, Sb and Hg by optical emission spectrometry and using a continuous flow chemical vapor generation of these elements (AsH 3 , SbH 3 , Hg 0 ) in the reaction with sodium tetrahydroborate. The effect of the concentration of helium in the plasma gas on excitation, vibrational and rotational temperatures and the electron number density in the discharge obtained from argon and mixtures of argon with helium was studied to evaluate changes in excitation conditions and their impact on the analytical performance of the plasma. It was found that the presence of 10-20% v/v of helium in the carrier/plasma gas is very convenient for the excitation of As, Sb and Hg introduced to the plasma via the volatile species generation reaction. In reference to limits of detection of 4.1 (As), 1.8 (Sb) and 1.4 (Hg) ng ml À1 , such a plasma has a considerably better analytical performance as compared to the plasma generated only in an argon atmosphere.
