Dispersionless atomic emission spectrometry with excitation in microwave plasma

High-resolution spectrometers with inductively coupled plasma burners as a source of excitation have been widely recommended for use in multielement atomic emission spectroscopy. Using these spectrometers, up to 60 elements can be determined simultaneously at the lower limit of detectable contents. In this paper, a combination of sample preparation and gas-chromatographic separation of volatile compounds of the elements to be determined is used for a dispersionless atomic emission determination of microamounts of metals forming covalent volatile hydrides, with the excitation of the gaseous sample in the microwave plasma. Their analysis in coal and plant matter is given as an example
