1、Designation:D716522Standard Practice forGas Chromatograph Based On-line/At-line Analysis forSulfur Content of Gaseous Fuels1This standard is issued under the fixed designation D7165;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、 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.Scope1.1This practice is for the determination of gas phasesulfur-containing compounds in high methane content gaseousfuels
3、 such as natural gas using on-line/at-line instrumentation,and continuous fuel monitors(CFMS).It has been successfullyapplied to other types of gaseous samples including air,digester,landfill,and refinery fuel gas.The detection range forsulfur compounds,reported as picograms sulfur,based uponthe ana
4、lysis of a 1 mL sample,is one hundred(100)to onemillion(1 000 000).This is equivalent to 0.1 to 1000 mg/m3.1.2 This practice does not purport to measure all sulfurspecies in a sample.Only gas phase compounds that aretransported to an instrument under the measurement conditionsselected are measured.1
5、.3 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.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 appr
