  • Apparatus and process for total sulfur determination
    Patent number: 5049508
    Abstract: The total sulfur content of samples consisting of chemical compounds is determined by the use of gas chromatographic separation of the sulfur and its flame-photometric detection. The samples are subjected to a catalytic reaction in a pipe reactor before the separation whereby all sulfur-containing compounds are completely converted into hydrogen sulfide. The pipe reactor is made from an aluminum oxide material in a purity of at least 99.8% of the corundum type.
