Description
1.1 This test method covers the determination of nonylphenol (NP), nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), and octylphenol (OP), extracted from water utilizing solid phase extraction (SPE), separated using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). These compounds are qualitatively and quantitatively determined by this method. This method adheres to single reaction monitoring (SRM) mass spectrometry.
1.2 The method detection limit (MDL) and reporting limit (RL) for NP, NP1EO, NP2EO, and OP are listed in Table 1.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
TABLE 1 MDL and Reporting Limits
| Analyte | MDLA (ng/L) |
Reporting RangeB (ng/L) |
|---|---|---|
| NP | 33 | 100-2000 |
| NP1EO | 9 | 100-2000 |
| NP2EO | 9 | 100-2000 |
| OP | 24 | 100-2000 |
A MDL Determined Following The Code of Federal Regulations, 40 CFR Part 136, Appendix B.
B Lowest Point of the Reporting Range is Calculated from the LV 1 Concentration Calibration Standard in Table 4.
