METHOD 8141A . ORGANOPHOSPHORUS COMPOUNDS BY GAS CHROMATOGRAPHY: CAPILLARY COLUMN TECHNIQUE. SCOPE AND APPLICATION. METHOD 8141 is a capillary gas chromatographic (GC) METHOD used to determine the concentration of ORGANOPHOSPHORUS (OP) COMPOUNDS . The fused- silica, open-tubular columns specified in this METHOD offer improved resolution, better selectivity, increased sensitivity, and faster analysis than packed columns. The COMPOUNDS listed in the table below can be determined by GC using capillary columns with a flame photometric detector (FPD) or a nitrogen- phosphorus detector (NPD). Triazine herbicides can also be determined with this METHOD when the NPD is used. Although performance data are presented for each of the listed chemicals, it is unlikely that all of them could be determined in a single analysis. This limitation results because the chemical and chromatographic behavior of many of these chemicals can result in co-elution. The analyst must select columns, detectors and calibration procedures for the specific analytes of interest in a study.
