Sulphur concentrations from 5 μg/g to 30 μg/g. Dissolution in a reducing acid containing antimony, which reduces the sulphur to hydrogen sulphide. The hydrogen sulphide is converted to zinc sulphide, which is then measured photometrically as methylene blue.

All current amendments available at time of purchase are included with the purchase of this document.
