METHOD 632 - CARBAMATE UREA PESTICIDES

Method 632 is applicable to the determination of carbamate and urea pesticides in industrial and municipal wastewater by high performance
liquid chromatography (HPLC). Note that this method provides for an optional Florisil column cleanup procedure, to aid in the elimination or
reduction of interferences, which may be encountered (caused by contaminants in solvents, reagents, glassware and other sample processing
EPA 600 CARBAMATE & UREA PESTICIDES MIXTURE
apparatus that lead to discrete artifacts or elevated baselines in liquid chromatograms).

METHOD 634 - THIOCARBAMATE PESTICIDES
Method 634 is applicable to the determination of thiocarbamate pesticides in industrial and municipal wastewaters. Sample extraction
and concentration steps in this method are similar to other 600 Series Methods. The separation and measurement of the compounds in the
extract is by alkali flame detector (AFD) gas chromatography. To aid in the elimination of interferences an optional silica gel column cleanup
procedure is provided. This method describes analytical conditions for a second gas chromatographic column that can be used to confirm
measurements made with the primary column, as well as the gas chromatograph/mass spectrometer (GC/MS) criteria appropriate for the
qualitative confirmation of these compound.
