Determination of imported and exported food fluoro-ene oxalate Residues
Gas chromatography - mass spectrometry
1 Scope
This standard specifies the fluorine-ene oxalate in food import and export of residual gas chromatography - mass spectrometry.
This standard applies to corn, celery, apples, peanuts, tea, beef, chicken, fish, honey, soy and milk-fluoro-ene acid residues
Detection and confirmation.
2 Method summary
Samples residual fluorine-ene oxalate extracted with ethyl acetate or acetonitrile. After extraction the organic phase was evaporated to dryness, the residue from ethyl acetate - cyclohexane
(1 + 1) dissolved by gel permeation chromatography (GPC) purification, eluent evaporated volume by gas chromatography - mass spectrometry in selected ion detection, external standard
Statutory amount.
