✦ Synopsis
A modified oxygen-flask method for total sulphur analysis using Arsenazo (III) as titration indicator and Chrome1 'A' wire as combustion-grate material has been used to analyse twelve Canadian coals of widely differing rank, ash, and sulphur content. The results indicate that the method is generally applicable to coal sulphur analysis. The endpoint unlike that of Thorin is sufficiently definite to permit use of the method by relatively untrained analysts. The precision of the method appears to be similar to that of the Eschka method.
