摘要：

A mass spectrometric isotope dilution method for the determination of sulphur in steels and certain alloys has been investigated. Addition of bromine in the dissolution of carbon steels was necessary for the complete conversion of sulphur into sulphate. The relative standard deviation was better than 1.5% for sulphur contents in the range 40-3,000 ppm. The results on standard materials were in good agreement with the certified values for samples of BCS, but lower than those for JSS and NBS. © 1979.
