The sulfur analysis started by Stragand is made by heating sulfur-containing sample in an oxygen atmosphere, with platinum as a catalyst, the sulfur oxide is adsorbed on heated silver net, and this net is weighed. It was found in the present series of experiments that this platinum could be substituted with copper oxide without any trouble in the analytical values of sulfur. Concurrent determination of carbon, hydrogen, and sulfur by filling this copper oxide and silver net in the combustion tube was carried out and good results were obtained. This could be applied with air stream in case of a series of substances whose sulfur is easily oxidized.
