1.1 This procedure covers the determination of bisphenol A (BPA) extracted from water utilizing solid phase extraction (SPE), separated using liquid chromatography (LC) and detected with tandem mass spectrometry (MS\/MS). BPA is qualitatively and quantitatively determined by this method. This method adheres to multiple reaction monitoring (MRM) mass spectrometry.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.3 The method detection limit (MDL) and reporting limit (RL) for BPA are listed in Table 1.<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n

TABLE 1 MDL and Reporting Range<\/p>\n

A<\/span><\/sup> MDL determined following the Code of Federal Regulations, 40CFR Part 136, Appendix B.<\/p>\n

B<\/span><\/sup> Lowest point of the reporting range, reporting limit, is calculated from the LV 1 concentration calibration standard in Table 4. Fig. 1 displays the signal\/noise ratio at the reporting limit.<\/p>\n
