Designation:D839622Standard Test Method forGroup Types Quantification of Hydrocarbons inHydrocarbon Liquids with a Boiling Point between 36 Cand 343 C by Flow Modulated GCxGC FID1This standard is issued under the fixed designation D8396;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 quantitative determinationof total n-paraffins,total i-paraffins,total naphthenes(cycloparaffins),total one ring(1R)and total two ring plus(2R+)aromatic hydrocarbons in hydrocarbon liquids having aboiling point between 36 C and 343 C by GCxGC(flowmodulated comprehensive two-dimensional gas chromatogra-phy).The method has been applied to aviation turbine fuels andis applicable to other low olefinic fuels in the stated boilingpoint range.1.2 This test method has an interim precision.An expandedfull interlaboratory study is to be completed in 5 years.Thetest method working concentration ranges in mass percent forwhich the interim precision has been determined are asfollows:Hydrocarbon TypeLower limit(mass percent)Upper limit(mass percent)Total i-paraffins22.024.3Total n-paraffins19.021.9Total naphthenes(cycloparaffins)34.336.7Total one ring aromatics18.721.8Total two ring plusaromatics0.51.91.3 This test method is applicable to other group typeconcentration ranges,to other hydrocarbon types such asselected individual components,for example,benzene,toluene,or n-paraffins by carbon number,or to other hydrocarbonstreams;however,precision has not been determined at thistime.A future ILS will include a variety of sample types andextend the reporting.1.4 This test method is not intended to determine unsatu-rated hydrocarbons,such as olefins,content which may inter-fere with the cycloparaffins;this test method is applicable tosamples with 1%by mass total olefins as determined byD1319.1.5 This test method is not intended to determine FAME(fatty acid methyl esters).For such applications,Test MethodD7797,IP 585,or equivalent test methods are available.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard test method does not mandate or describea specific software package for data processing and display.Any commercially available GCxGC software used for dataprocessing and display shall meet the requirements for thecalculation of the results.Appendix X1 provides some guide-lines.1.8 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.1.9 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:D1319 Test Method for Hydrocarbon Types in Liquid Petro-leum Products by Fluorescent Indicator AdsorptionD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD4307 Practice for Preparation of Liquid Blends for Use asAnalytical StandardsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6730 Test Method for Determination of Individual Com-ponents in Spark Ignition Engine Fuels by 100-Metre1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0L on Gas Chromatography Methods.Current edition approved April 1,2022.Published April 2022.DOI:10.1520/D8396-22.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.1Capillary(with Precolumn)High-Resolution Gas Chro-matographyD7797 Test Method for Determination of the Fatty AcidMethyl Esters Content of Aviation Turbine Fuel UsingFlowAnalysisbyFourierTransformInfraredSpectroscopyRapid Screening MethodE355 Practice for Gas Chromatography Terms and Relation-shipsE594 Practice for Testing Flame Ionization Dete
