A method for the determination of Acetamiprid residue in cucumber samples was de- veloped using Gas Chromatography-Negative Chemical Ionization-Mass Spectrometry （GC-NCI- MS）. The sample was extracted with ethyl acetate, purified by graphitized carbon black （GCB）, and determined by gas chromatography with negative chemical ionization mass spectrometric detection in the selected ion monitoring mode. Average fortified recoveries range from 85.3% to 99.0% with relative standard deviations from 4.0% to 4.7%.The linear ranges are from 0.004mg/mL to 1.0mg/mL with correlation coefficient of 0.996, and the limit of quantification is 5μg/kg. A quick, easy, sensitive method was used to determine acetamiprid residues in cucumber.
