英文摘要	a new method was established for the direct, rapid and quantitative analysis of pesticide residues, dimethoate chlorothalonil and malathion by low temperature plasma (ltp) ionization miniature ion trap mass spectrometer. the ltp ionization probe and sample inlet of ion trap mass spectrometry were enclosed in a metal cavity. with non-contact heating, the samples placed on the sample platform were desorbed into gaseous phase and ionized by ltp ionization probe. the results showed that closed ionization had an edge over the opened ionization. the quantitative analysis of 3 pesticides within the range of 0.5-10 mg/l was realized by optimizing heating time and flow rate of air, and the relative standard deviations of signal intensity is less than 11%. lods of pesticide, which were obtained within 5 s, were as low as several hundred pictograms. the results showed that the method could be used for the analysis of pesticide residue on green and organic fruits or vegetables.
