Determining the concentration of sulphur in coal

摘要

This invention relates to a method for determining the concentration of sulphur in coal and to apparatus which enables this method to be put into practice. The method involves measuring the intensities of the X-ray fluorescent radiations from iron and sulphur atoms in a sample of coal which has been excited by X-ray radiation. The measures of the intensities are combined mathematically to give an output from which the concentration of sulphur in the coal may be determined. Using the apparatus described the concentration of sulphur in a sample of coal can be determined quickly and accurately by an unskilled worker.
