“…Beenakker and co-workers (13) reported the effect of KCl on emission intensities of some elements when a pneumatic nebulizer was used. Abdallah et al (14) and Jin et al (15) reported the EIE effects in an MIP when an ultrasonic nebulizer was used. The explanations about this effect have not been satisfactory yet.…”

“…Analytical applications of the surface wave plasmas Surface wave plasmas are now used in several analytical laboratories. Although some work has been done on direct liquid sample analysis [14,22] with the surface wave plasma, most of the analytical efforts have been devoted to gas phase sample analysis. The samples that have been analyzed are atomic (Hg cold vapor) [23] and molecular gases (Cl 2 , I 2 , Br 2 ) [15,24,25] produced by various chemical reactions.…”

“…Although work has been performed with microwave induced and surface wave plasmas for solution analysis [13,14], their main application in analytical chemistry has been the analysis of gas phase samples [15,16] and predominantly as element specific detectors for gas chromatography [3,[17][18][19][20]. This is due to the low power generally associated with microwave induced plasma generation, as the resulting low gas temperature does not provide efficient desolvation and atomization capabilities.…”

The use of microwave induced plasmas, particularly of surface wave plasmas, as detectors in atomic emission spectrometry for elemental analysis is reviewed. Surface wave plasmas have been produced at low HF power and used as gas chromatographic detectors. The analytical performances for the detection of non-metals with a Fourier transform spectrometer and a two-channel filter unit are reported. The excitation behavior of non-metals in helium-based mixed gas-plasmas has also be studied. In particular, the effect of power and of nitrogen concentration on the bromine emission has been systematically investigated. A nine-fold improvement of the detection limits for bromine can be obtained in a high power (900 W) helium-nitrogen (0.1-0.2%) plasma.

“…This source has the advantages of low cost, low gas consumption, and ease of use over an ICP [1]. However, an MIP such as the one produced by either a Beenakker cavity [2,3], a Surfatron [4,5] or a microwave torch [6] has some serious limitations, for example, a low power (up to 500 W) and its low tolerance to liquid aerosols.…”

An annular-shaped, high power nitrogen microwave induced plasma (N(2)-MIP) produced at atmospheric pressure by an Okamoto cavity, as a new excitation source for atomic emission spectrometry (AES), has been used for the simultaneous determination of bismuth and tellurium in steels with the hydride generation method. Under the optimized experimental conditions, the best attainable detection limits at the Bi I 195.389 nm and Te I 200.200 nm lines were 110 and 86 ng/ml for bismuth and tellurium, respectively. The linear dynamic ranges for bismuth and tellurium were 300 to 30,000 ng/ml. The presence of several diverse elements was found to cause a more or less depressing interference with the proposed technique. When bismuth and tellurium in steels were determined, a large amount of Fe(III) in the solution caused a severe depressing interference, while the presence of Fe(II) showed little or no significant interference. Of the several interference-releasing agents examined, l-ascorbic acid was found to be the most preferable to reduce Fe(III) to Fe(II) prior to hydride generation. The concentrations of bismuth and tellurium in steels were determined by the proposed technique. The results obtained by this method were in good agreement with their certified values.
