Designation:D567315Standard Test Method forElements in Water by Inductively Coupled PlasmaMassSpectrometry1This standard is issued under the fixed designation D5673;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.Scope*1.1 This test method covers the determination of dissolvedelements in ground water,surface water,and drinking water.Itmay also be used for the determination of total-recoverableelements in these waters as well as wastewater.21.2 This test method should be used by analysts experiencedin the use of inductively coupled plasmamass spectrometry(ICP-MS),the interpretation of spectral and matrix interfer-ences and procedures for their correction.1.3 It is the users responsibility to ensure the validity of thetest method for waters of untested matrices.1.4 Table 1 lists elements for which the test method applies,with recommended masses and typical estimated instrumentaldetection limits using conventional pneumatic nebulization.Actual working detection limits are sample dependent and,asthe sample matrix varies,these detection limits may also vary.In time,other elements may be added as more informationbecomes available and as required.1.4.1 This method covers the analysis of mine dewateringgroundwater and wastewater effluent in the range of 2120g/L dissolved antimony and 3200 g/L dissolved arsenic.1.4.2 This method covers the analysis of metallurgicalprocessing cyanide solutions in the range of 1500 g/Ldissolved gold.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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:3D1066 Practice for Sampling SteamD1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on WaterD3370 Practices for Sampling Water from Closed ConduitsD5810 Guide for Spiking into Aqueous SamplesD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water AnalysisE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE1601 Practice for Conducting an Interlaboratory Study toEvaluate the Performance of an Analytical MethodE1763 Guide for Interpretation and Use of Results fromInterlaboratory Testing of Chemical Analysis Methods(Withdrawn 2015)43.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this standard,refer toTerminology D1129.3.2 Definitions of Terms Specific to This Standard:3.2.1 calibration blank,na volume of water containingthe same acid matrix as is in the calibration standards(see11.1).3.2.2 calibration standards,na series of known standardsolutions used by the analyst for calibration of the instrument(that is,preparation of the analytical curve)(see Section 11).3.2.3 calibration stock solution,na solution preparedfrom the stock standard solution(s)to verify the instrumentresponse with respect to analyte concentration.3.2.4 dissolved,adjcapable of passing through a 0.45-mmembrane filter.1This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.05 on Inorganic Constituentsin Water.Current edition approved July 1,2015.Published August 2015.Originallyapproved in 1996.Last previous edition approved in 2010 as D5673 10.DOI:10.1520/D5673-15.2EPA Test Method:Determination of Trace Elements in Waters and Wastes byInductively Coupled PlasmaMass Spectrometry,Method 200.8.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.*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 3.2.5 interference check sample A(ICSA),na solutioncontaining matrix elements at environmental levels that resultin interferences on target low level analytes.3.2.5.1 DiscussionICSA is different from the mixed ele-ment standards in 8.4,which are intended for instrumentcalibration,not for checking interferences.The interferencesformed in the ICP can be corrected for by use of element-specific correction equations,collision cell technology withquadrupole-based ICP-MS,or high-resolution ICP-MS
