3、n light petroleum liquids.Thistest method is applicable to distillates,gasoline motor fuels(including those containing oxygenates)and other petroleumliquids with a final boiling point of approximately 230C(450F)or lower at atmospheric pressure.The applicableconcentration range will vary to some exte
4、nt depending on thenature of the sample and the instrumentation used;however,inmost cases,the test method is applicable to the determinationof individual sulfur species at levels of 0.1 to 100 mg/kg.1.2 The test method does not purport to identify all indi-vidual sulfur components.Detector response
5、to sulfur is linearand essentially equimolar for all sulfur compounds within thescope(1.1)of this test method;thus both unidentified andknown individual compounds are determined.However,manysulfur compounds,for example,hydrogen sulfide andmercaptans,are reactive and their concentration in samplesmay
