1、Designation:D757416Standard Test Method forDetermination of Bisphenol A in Environmental Waters byLiquid Chromatography/Tandem Mass Spectrometry1This standard is issued under the fixed designation D7574;the number immediately following the designation indicates the year oforiginal adoption or,in the
2、 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 procedure covers the determination of bisphenol A(BPA)extracted from water utilizing sol
3、id phase extraction(SPE),separated using liquid chromatography(LC)and de-tected with tandem mass spectrometry(MS/MS).BPA isqualitatively and quantitatively determined by this method.This method adheres to multiple reaction monitoring(MRM)mass spectrometry.1.2 The values stated in SI units are to be
4、regarded asstandard.No other units of measurement are included in thisstandard.1.3 The method detection limit(MDL)and reporting limit(RL)for BPA are listed in Table 1.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the
5、 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:2D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD2777 Practice for Determination of P
