1、Designation: D7574 16Standard 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
2、 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 procedure covers the determination of bisphenol A(BPA) extracted from water ut
3、ilizing solid 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
4、 units are to be 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
