description

Summary For the determination of about 1 μg hydrogen in nonvolatile organic compounds 10–40 μg of the substance are burnt at > 1000°C in a slow stream of oxygen. The water generated is converted to H 2 S by reaction with carbon disulfide in a flow of nitrogen at 500°C catalyzed by α-Al 2 O 3 . The hydrogen sulfide is argentimetrically titrated by a potentiometric method. The standard deviation of the method is ± 10 ng H. There are no interferences by N, S, and the halogens.
