ABSTRACT:
A method for the determination of sulfur by which sulfur is reduced to volatile hydrogen sulfide gas and swept into a D.C. plasma where it is detected by vacuum ultraviolet atomic emission spectrometry at 180.7 nm. The method makes possible the determination of trace levels of sulfur in samples where the matrix would normally result in spectral and/or chemical interferences.
