| Abstract: | The clean-up of the ethylacetate extracts of 31 common crops with the aid of liquid chromatography on polysterene gel is described. With a few exceptions, e.g. onions, the pesticide residue can be determined directly in the eluate gas-chromatographically using the electron capture or the flame photometric detector. |
