Designation:D802817Standard Test Method forMeasurement of Dissolved Gases Methane,Ethane,Ethylene,and Propane by Static Headspace Sampling andFlame Ionization Detection(GC/FID)1This standard is issued under the fixed designation D8028;the number immediately following the designation indicates the year oforiginal adoption or,in the case 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.Scope1.1 This test method covers the determination of the dis-solved gases methane,ethane,ethylene,and propane indrinking,waste,and ground waters,including domestic wellswhether naturally occurring or resulting from commercialactivities,or both.This test method has an analytical rangefrom 10 g/L to 11 000 g/L for methane,and 10 g/L to 5000g/L for ethane,ethylene,and propane.If a sample has adissolved gas concentration above the calibration range,thesample would require dilution.Other analytical ranges may beused as long as the instrument calibration encompasses thedesired range and demonstrates adequate linearity.1.2 This test method is applicable to samples collected at anominal ambient pressure.Samples collected under highpressures,that is,above ambient pressure,may not be accu-rately analyzed using this method.1.3 This test method is applicable to a variety of dissolvedgases;however,for the present standard,only methane,ethane,ethylene,and propane were validated.In order to validate fora gas not listed in this method,the analyst would need toestablish the saturation concentration of the new gas,andestablish a valid curve,method detection limits,and demon-stration of capability following the procedures outlined in thismethod.1.4 It is the analysts responsibility to ensure the validity ofthis test method for dissolved gases other than methane,ethane,ethylene,and propane and other sample matrices.1.5 UnitsThe values stated in SI units are to be regardedas the standard.No other units of measurement are included inthis standard.1.6 A single laboratory study was done in order to establishprecision and bias for the surrogate(see Section 16).1.7 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 environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD8006 Guide for Sampling and Analysis of Residential andCommercial Water Supply Wells in Areas of Explorationand Production(E&P)OperationsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE355 Practice for Gas Chromatography Terms and Relation-shipsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 Federal Standards:40 CFR Part 136,Appendix B Definition and Procedure forthe Determination of the Method Detection Limit,Revi-sion 1.113PA-DEP 3686 Light Hydrocarbons in Aqueous Samples viaHeadspace and Gas Chromatography with Flame Ioniza-tion Detection(GC/FID),Revision 0,April 20124SW-846 Test Methods for Evaluating Solid Waste:Physical/1This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.06 on Methods forAnalysis forOrganic Substances in Water.Current edition approved Nov.1,2017.Published December 2017.DOI:10.1520/D8028-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from U.S.Government Printing Office,Superintendent ofDocuments,732 N.Capitol St.,NW,Washington,DC 20401-0001,http:/www.access.gpo.gov.4Available from Pennsylvania Department of Environmental Protection(PA-DEP),Headquarters,Rachel Carson State Office Building,400 Market Street,Harrisburg,PA 17101,http:/www.dep.state.pa.us.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 Chemical Methods,Update V,Chapter Four,Revision 5,July 20145SW-846,Method 5021 Volatile Organic Compounds
