1、Designation:D562319Standard Test Method forSulfur Compounds in Light Petroleum Liquids by GasChromatography and Sulfur Selective Detection1This standard is issued under the fixed designation D5623;the number immediately following the designation indicates the year oforiginal adoption or,in the case
2、of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of volatilesulfur-containing compounds in light petroleu
3、m liquids.Thistest method is applicable to distillates,gasoline motor fuels(including those containing oxygenates)and other petroleumliquids with a final boiling point of approximately 230 C(450 F)or lower at atmospheric pressure.The applicableconcentration range will vary to some extent depending o
4、n 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 mg kg to100 mgkg.1.2 The test method does not purport to identify all indi-vidual sulfur components.Detector response to sulfur
5、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 change du
6、ring sampling and analysis.Coincidently,thetotal sulfur content of samples is estimated from the sum of theindividual compounds determined;however,this test method isnot the preferred method for determination of total sulfur.1.3 The values stated in SI units are to be regarded asstandard.The values
7、given in parentheses after SI units areprovided for information only and are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and
