Designation:D811017Standard Test Method forElemental Analysis of Distillate Products by InductivelyCoupled Plasma Mass Spectrometry(ICP-MS)1This standard is issued under the fixed designation D8110;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.INTRODUCTIONCertain elements present in distillate petroleum can either adversely or constructively affect theperformance of the product and thus impacts its utility and market value.The industry has traditionallyrelied on inductively coupled plasma atomic emission spectrometry(ICP-AES)or atomic absorptionspectrometry(AAS)to determine the concentration of these elements present in the product.Asspecifications have become more stringent,a need to extend these measurements to lowerconcentrations by employing more sensitive measurement technologies has arisen.Inductivelycoupled plasma mass spectrometry is ideal for this application for most distillate petroleum products.By applying ICP-MS for elemental analysis of these products,the concentration range of detectableelements can be extended from low to sub ng/g(ppb mass)to 1000 ng/g(ppb mass)for someelements.1.Scope1.1 This test method describes the procedure for the deter-mination of trace elements in light and middle distillatepetroleum products using inductively coupled plasma massspectrometry(ICP-MS).1.2 This test method should be used by analysts experiencedin the use of inductively coupled plasma mass spectrometry(ICP-MS)with knowledge of interpretation of spectral,isobaric,polyatomic,and matrix interferences,as well asprocedures for their correction or reduction.1.3 The table in 6.1 lists elements for which the test methodapplies along with recommended isotope.Actual workingdetection limits are sample dependent and,as the samplematrix varies,these detection limits may also vary.1.4 The concentration range of this test method is typicallyfrom low to sub ng/g(ppb mass)to 1000 ng/g(ppb mass),however the precision and bias statement is specified for asmaller concentration range based on test samples analyzed inthe ILS,see the table in Section 18.The test method may beused for concentrations outside of this range;however,theprecision statements may not be applicable.1.4.1 This test method shall be further developed to extendthat table to include additional elements.1.5 This test method uses metallo-organic standards(orga-nometallic or organosoluble metal complex)for calibration anddoes not purport to quantitatively determine insoluble particu-lates.Analytical results are particle size dependent,and lowresults are obtained for particles larger than a few micrometersas these particles may settle out in the sample container and arenot effectively transported through the sample introductionsystem.1.6 Elements present at concentrations above the upper limitof the calibration curves can be determined with additional,appropriate dilutions and with no degradation of precision.1.7 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.Specific warningstatements are given in 8.2,8.7,and Section 9.1.9 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.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.03 on Elemental Analysis.Current edition approved May 1,2017.Published May 2017.DOI:10.1520/D8110-17.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 2.Referenced Documents2.1 ASTM Standards:2D3605 Test Method for Trace Metals in Gas Turbine Fuelsby Atomic Absorption and Flame Emission SpectroscopyD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD
