Apphcatisn of an Oscillating - mirror Rapid - scanning Spectrometer to Simultaneous Multi - element Microwave Plasma Emission Spectrometry
نویسندگان
چکیده
The potential value of an oscillating-mirror rapid-scanning spectrometer as a detector for simultaneous multi-element emission spectrometry is demonstrated. A microwave argon plasma was used as the emission source with a carbon cup sampling device for analyte introduction. Analy tical graphs for bismuth, cadmium, manganese and magnesium prepared sirnulta neously are shown. The sensitivity of this system for cadmium, manganese and magnesium is a t the nanogram level. The spectrometer has a wide optical range of 200-930 nm that can be scanned in a single sweep and a large dynamic range as radiation is detected by a photomultiplier tube.
