METHOD 8325 – BENZIDINES & NITROGEN PESTICIDESMethod 8325 describes the use of high performance liquid chromatography (HPLC), coupled with particle beam (PB) mass spectrometry (MS),for the determination of the solvent extractable nonvolatile benzidines and nitrogen-containing pesticides in water and wastewater.MS PERFORMANCE CHECK SOLUTION BENZIDINESAND NITROGEN-CONTAINING PESTICIDESEPA METHOD 8325EPA 8000F2456 100mg Decafl uorotriphenylphosphine oxideF2456S 5mL 100ug/ml AcetonitrileF2456JS 1mL 100ug/ml AcetonitrileSURROGATE SPIKING SOLUTIONS BENZIDINESAND NITROGEN-CONTAINING PESTICIDESEPA METHOD 83253,3’-Dichlorobenzidine-D 6FD28S 1.2mL 1000ug/mL in BenzeneBenzidine-D 8F2455S 5mL 100ug/mL in MethanolF2455JS 1mL 100ug/mL in MethanolF2456 10mg Decafl uorotriphenylphosphine oxideMETHOD 8330 – NITROAROMATICS & NITRAMINESMethod 8330 is applicable for determination of nitroaromatics and nitramines by high performance liquid chromatography (HPLC). This methodis intended for the trace analysis of explosive residues by high performance liquid chromatography using a UV detector. It provides for a saltingoutextraction procedure for low concentration (parts per trillion or nanograms per liter) of explosive residues in surface or ground water.NITROAROMATICS & NITRAMINES SOLUTIONS KITEPA METHOD 8330 2-Amino-4,6-dinitrotoluene Solution 4-Amino-2,6-dinitrotoluene Solution m-Dinitrobenzene Solution 2,4-Dinitrotoluene Solution 2,6-Dinitrotoluene Solution Hexahydro-1,3,5-trinitro-1,3,5-triazine(water added) Solution Nitrobenzene Solution o-Nitrotoluene Solution m-Nitrotoluene Solution p-Nitrotoluene Solution Octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine(water added) Solution Tetryl (water added) Solution 1,3,5-Trinitrobenzene Solution 2,4,6-Trinitrotoluene Solution5mL Solutions of each, in the appropriate solvent - (14 component kit)NN8330-1S KITUnless otherwise stated, for all the neat Standards Grade products, the purity has a deviation of +/- 0.5%, and for the solutions,the concentration has a deviation of +/- 5%. We guarantee our neats to be +/- 0.5% of the labeled purity. We guarantee oursolutions to be +/- 5% of the labeled concentration. +/- 0.5% and +/- 5% are the uncertainties that have been assigned to thepurity and concentration. 247
