Abstract: The uses for which hydrogen sulfide determinations are made and the requirements imposed on them vary widely. For some purpose a qualitative test is sufficient, while for others exact quantitative determinations are necessary. In some cases the instantaneous value over a period of time is more desirable. The concentration of the hydrogen sulfide in the gas which is being analyzed varies from as little as a few hundredths of a grain to several thousand grains per hundred cubic feet. In addition mercaptans and unsaturated compounds may be present and, if present, may give erroneously high results. Because of these facts it would be that a variety of methods would be required to meet the requirements of all possible cases, and, accordingly, a number of different methods have been developed. They are of two types: the colorimeter tests used for qualitative or semi-qualitative test, and the absorption methods used for quantitative determinations.
