title: Analysis of acetamiprid in vegetables using gas chromatography-tandem mass spectrometry.
abstract: A new analytical method has been validated for determining the insecticide acetamiprid in vegetables using gas chromatography (OC) and different mass spectrometric detection techniques, such as full-scan mass spectrometry (MS), and tandem mass spectrometry (MS/MS). For this purpose, a previous extraction of the vegetable sample was carried out with ethyl acetate. In GC-MS/MS, the lowest detectable concentration was 0.001 mg kg(-1), the average recovery rates at various fortification levels (0.015 and 0.030 mg kg(-1)) ranged between 82.4 and 85.7% and the relative standard deviations were lower than 12.2% in all cases.
