High resolution chemically bonded fused‐silica capillary gas chromatography of organochlorine insecticides and related compounds in arable soil samples

Abstract

measured and calculated. OV-17 CB-FSC showed the best separability among the three CB-FSCs employed and was applied to analysis of extracts from several soil samples with minimum clean-up procedure. The chromatograms obtained demonstrated steady baseline tracings free of interference.Electron capture gas chromatography with three chemically bonded fused-silica capillary columns (CB-FSCs), OV-17, OV-1701, and SE-52, was performed to evaluate peakseparabilityof 28 organochlorine insecticides and related compounds. Relative retention times and relative peak heights to aldrin were Residue data from soil samples were also tabulated.
