Abstract
The accurate analysis of sulphur and sulphur compounds in plant material has become a critical issue as a consequence of reduced availability of the element from the environment. A new application of a reproducible technique has been developed for the determination of sulphur in wheat grain using X-ray fluorescence spectrometry. This new application compares favourably with traditional wet chemical methods especially as it is non-destructive. The sulphur content in wheut yruin measured by X-ray ffuorescence spectrometry was found to have a lower variability and the speed of analysis was more rapid in comparison with the chemical method, enabling a faster throughput of samples. Because sample preparation is very important for accurate analysis, the problems associated with oven drying, milling and of pressing during pellet formation are discussed.
