[Simultaneous, gas-chromatographic determination of ethyleneoxide, ethylenechlorohydrine and ethyleneglycol in grain (author's transl)].

The not comminuted grain (10 g) is extracted for 24 hrs (25 degrees C) with 5 ml methanol (shaking machine), then the fluid phase is separated by centrifugal filtration and directly injected into the GC (10 mu). The GC starting temperature (60 degrees C) is adjusted by cooling the oven with Co2. Yield: EO 73% (concentr.
