Designation:D2163141Standard Test Method forDetermination of Hydrocarbons in Liquefied Petroleum(LP)Gases and Propane/Propene Mixtures by GasChromatography1This standard is issued under the fixed designation D2163;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.1NOTESummary of Changes section was editorially added in March 2014.1.Scope*1.1 This test method covers the quantitative determinationof individual hydrocarbons in liquefied petroleum(LP)gasesand mixtures of propane and propene,excluding high-puritypropene in the range of C1to C5.Component concentrationsare determined in the range of 0.01 to 100 volume percent.1.2 This test method does not fully determine hydrocarbonsheavier than C5and non-hydrocarbon materials,and additionaltests may be necessary to fully characterize an LPG sample.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1265 Practice for Sampling Liquefied Petroleum(LP)Gases,Manual MethodD1835 Specification for Liquefied Petroleum(LP)GasesD2421 Practice for Interconversion of Analysis of C5andLighter Hydrocarbons to Gas-Volume,Liquid-Volume,orMass BasisD2598 Practice for Calculation of Certain Physical Proper-ties of Liquefied Petroleum(LP)Gases from Composi-tional AnalysisD3700 Practice for Obtaining LPG Samples Using a Float-ing Piston CylinderD6729 Test Method for Determination of Individual Com-ponents in Spark Ignition Engine Fuels by 100 MetreCapillary High Resolution Gas ChromatographyE355 Practice for Gas Chromatography Terms and Relation-shipsE594 Practice for Testing Flame Ionization Detectors Usedin Gas or Supercritical Fluid ChromatographyE1510 Practice for Installing Fused Silica Open TubularCapillary Columns in Gas Chromatographs2.2 Canadian General Standards Board Publications:3CAN/CGSB 3.0 No.14.3 Standard Test Method for theIdentification of Hydrocarbon Components in AutomotiveGasoline Using Gas Chromatography2.3 Gas Processors Association:4GPA Std 2145-03 for hexane3.Terminology3.1 Definitions:3.1.1 Additional terminology related to the practice of gaschromatography can be found in Practice E355.3.1.2 liquefied petroleum gas(LPG),nhydrocarbon gasesthat can be stored or handled in the liquid phase throughcompression or refrigeration,or both.3.1.2.1 DiscussionLPGs generally consist of C3and C4alkanes and alkenes or mixtures thereof and containing lessthan 10 volume percent of higher carbon number material.Vapor pressure does not normally exceed 2000 kPa at 40C.3.2 Definitions of Terms Specific to This Standard:3.2.1 propane/propene mixtures,nmixtures primarilycomposed of propane and propene where one of these compo-nents is usually in the concentration range of 30 to 85 mass%with the other comprising the majority of the remainder.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.D0.03 on Propylene.Current edition approved Jan.1,2014.Published January 2014.Originallyapproved in 1963.Last previous edition approved in 2007 as D216307.DOI:10.1520/D2163-14E01.2For 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 CGSB,Canadian General Standards Board,Gatineau,CanadaK1A 1G6.Visit the CGSB website,www.pwgsc.gc.ca/cgsb/4Available from Gas Processors Association(GPA),6526 E.60th St.,Tulsa,OK74145,http:/.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1“Commercial Propane in Specification D1835 is typically thissort of product mixture.3.2.1.1 DiscussionOther components may be present,usually at less than 10 mass%.4.Summary of Test Method4.1 An LPG sample is analyzed via either liquid or gassampling valves by gas chromatography and compared tocorresponding components separated under identical operatingconditions from a reference standard mixture of known com-position or from use of pure hydrocarbons.The chromatogramof the sample is interpreted by comparing peak retention timesand areas with those obtained for the reference standardmixture or pure hydrocarbons.5.Significance and Use5.1 The hydrocarbon component distribution of l
