Abstract |
Tables of relative retention data are presented for 95 organochlorine and organophosphorus pesticidal compounds at column oven temperatures from 170 to 204 degrees C in 2 degree increments. Studies revealed a linear relationship between column temperature and relative retention ratios; thus, by obtaining precise values by gas-liquid chromatograhy for a number of pesticidal compounds at 170, 185, and 200 degrees C, a computer program was developed to obtain RRT (A or P) values at all 2 degree increments from 170 to 204 degrees C, the customary limits in the gas-liquid chromatography of pesticides. The tables are valuable in the tentative identification of pesticidal peaks resulting from the chromatography of sample extracts for multiresidue assessment. |
