Fig. I Reflectance scan of a chromatogram track with 300 ng substance per chromatogram zone 1 = azinphos methyl, 2 = azinphos ethyl, 3 = parathion methyl, 4 = fenitrothion, 5 = parathion ethyl + phoxim.

Azinphos ethyl (h/ f 20-25), malathion (h/ f 40-45) and diazinone (h/ f 47-52) yielded white chromatogram zones on a blue background immediately. Before in situ quantitation the chromatogram was dried in the air until no film of moisture could be seen on the layer surface. It was then dried completely in a stream of warm air whereby the blue coloration of the background changed to brown (Fig. 1). The visual detection limits were 200 ng substance per chromatogram zone.

Fig. 2 Reflectance scan of a chromatogram track with 500 ng azinphos ethyl (1), 580 ng malathion (2) and 590 ng diazinone (3) per chromatogram zone.

Demeton-S-methyl sulfone (hRf 0-5), dimethoate (h/ f 5-10), demeton-S-metlq (hRf 20-25), triazophos (h/ f 40-45), azinphos-methyl (hRf 40-45), azinphos-ethj (hRf 50-55), malathion (h/ f 60-65), parathion-methyl (hRf 75-80) and parathioo ethyl (h/ f 80-85) yielded yellow to brown chromatogram zones on a light brown bact ground, with thiophosphate insecticides with P = S double bonds appearing as brow zones and those with single P — S bonds as yellow zones.

Of the compounds listed in Table 10.1, all except dimethoate and azinphos-methyl exist as liquids at normal temperature and pressure. Looking through the table, it can be seen that there is considerable variation in both water solubility and vapor...
