本方法用于测定气态碳氢化合物和由C3和/或C4碳氢化合物组成的典型液化石油气（LPG）中的硫化氢（H2S）、硫醇硫（RSH）和羰基硫（COS）。还包括液化石油气中硫醇硫的测定，该液化石油气可能含有多种碳氢化合物类型，从乙烷到汽油沸点碳氢化合物，如戊烷和己烷。每种硫类型可从小于1至数千质量ppm的硫（每100立方英尺小于0.1至数千格令）中确定。

This method is for determining hydrogen sulfide (H2S), mercaptan sulfur (RSH) and carbonyl sulfide (COS) in gaseous hydrocarbons and in typical liquefied petroleum gas (LPG) consisting of C3 and/or C4 hydrocarbons. Also covered is the determination of mercaptan sulfur in LPG which may contain a wide range of hydrocarbon types ranging from ethane to such gasoline boiling range hydrocarbons as pentane and hexane. Each sulfur type can be determined from less than 1 to several thousand mass-ppm sulfur (less than 0.1 to several thousand grains per 100 cu ft).
