[Determination of fluoroacetatamide and fluoroacetic acid by capillary gas chromatography]

A rapid qualitative and quantitative analysis of fluoroacetatamide and fluoroacetic acid in rodenticides by capillary gaschromatography was described in this paper. Isoamyl alcohol was used as the internal standard. The determination curves of fluoroacetatamide and fluoroacetic acid in rodenticides were linear in the ranges of 0.0625-4 mg/ml and 0.625-20 mg/ml. The detection limits of fluoroacetatamide and fluoroacetic acid were 31.25 micrograms/ml (32.5 ng) and 625 micrograms/ml (625 ng), 87.5% and 30% of rodenticides sold in Taiyuan ground market from May, 1995 to May, 1996 contain fluoroacetatamide and fluoroacetic acid.
