About This Item
Full Description
1.1 This procedure covers the determination of Diisopropyl Methylphosphonate (DIMP), Ethyl Methylphosphonic Acid (EMPA), Isopropyl Methylphosphonic Acid (IMPA), Methylphosphonic Acid (MPA) and Pinacolyl Methylphosphonic Acid (PMPA), referred to collectively as organophosphonates (OPs) in this test method, in soil. This method is based upon solvent extraction of a soil by pressurized fluid extraction (PFE). The extract is filtered and analyzed by liquid chromatography/tandem mass spectrometry (LC/MS/MS). OPs are qualitatively and quantitatively determined by this method.
1.2 Units - The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The Method Detection Limit (MDL), electrospray ionization (ESI) mode and Reporting Range for the OPs are listed in Table 1.
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 Method Detection Limit and Reporting Range
| Analyte | ESI Mode | MDL (PPB) | Reporting Range (PPB) |
|---|---|---|---|
| Diisopropyl methylphosphonate | Positive | 2.7 | 40-2000 |
| Ethyl methylphosphonic acid | Negative | 2.3 | 40-2000 |
| Ethyl methylphosphonic acid | Positive | 1.3 | 40-2000 |
| Isopropyl methylphosphonic acid | Negative | 5.7 | 40-2000 |
| Isopropyl methylphosphonic acid | Positive | 2.8 | 40-2000 |
| Methylphosphonic acid | Positive | 8.7 | 40-2000 |
| Pinacolyl methylphosphonic acid | Negative | 5.3 | 40-2000 |
