METHOD 8321/8321A/8321B - ORGANOPHOSPHOROUS
Method 8321 is applicable to the determination, by high performance liquid chromatography (HPLC), coupled with either thermospray-mass
spectrometry (TSP-MS), and/or ultraviolet (UV), of disperse azo dyes, organophosphorus compounds, and Tris-(2,3-dibromopropyl) phosphate,
in wastewater, ground water, sludge, soil/sediment matrices, and chlorinated phenoxyacid compounds, and their esters. Quantitative analysis
is performed by TSP/MS, using an external standard approach. Sample extracts can be analyzed by direct injection into the thermospray or
onto a liquid chromatographic-thermospray interface. Note that detection is achieved both by negative ionization (discharge electrode) and
positive ionization, with a single quadrupole mass spectrometer. Since this method is based on an HPLC technique, the use of ultraviolet (UV) EPA 8000
detection is optional for routine samples

METHOD 8330 - NITROAROMATICS & NITRAMINES
Method 8330 is applicable for determination of nitroaromatics and nitramines by high performance liquid chromatography (HPLC). This method
is intended for the trace analysis of explosive residues by high performance liquid chromatography using a UV detector. It provides for a
salting- out extraction procedure for low concentration (parts per trillion or nanograms per liter) of explosive residues in surface or ground water.
