The determination of sulphur in rocks, soils and sediments by pyrohydrolysis/ion chromatography has been modified to reach lower detection limits of the order of 2 μg g −1 . Thirty‐one standard reference materials containing sulphur at levels ranging from 3 to about 900 μg g −1 have been analysed in triplicate. In general, the comparison of the results with those published is favorable. The method is also applicable to organic‐rich samples as demonstrated by the analysis of NBS samples (citrus leaves, tomato leaves, bovine liver).
