Determination of total sulfur in thirty one geochemical reference materials using an inductively coupled plasma-atomic emission spectrometer fitted with a semiconductor photodiode detector

The total sulfur contents of thirty one geochemical reference materials wer e determined using an inductively coupled plasma-atomic emission spectromet er fitted with a semiconductor photodiode detector. Most samples were decom posed using an HF-aquo regia, digestion. However, a few were incompletely d ecomposed by simple acid digestion, and these were decomposed by a fusion m ethod. The agreement between the analytical results from this work and publ ished data is generally good.
