AB  - Ion mobility spectrometry (IMS) has become a potential technique for the rapid 
      detection of organophosphorus pesticides (OPPs). However, using only the 
      commonly-used reactant ion (Ac)(2)H(+)(H(2)O) (n) , some OPPs are difficult to 
      distinguish due to their severely overlapping ion peaks. In this study, the 
      switching of reactant ions ((Ac)(2)H(+)(H(2)O) (n) , O(2) (-)(H(2)O) (n) and 
      Cl(-)(H(2)O) (n) ) in a stand-alone photoionization ion mobility spectrometer was 
      realized by on-line switching the polarity of high voltage and dopant species. 
      Multiple reactant ions were employed to establish the characteristic K (0) 
      patterns for the tested OPPs, including fenthion, dursban, dimethoate, malathion, 
      fenitrothion, imidan and isocarbophos. The tested OPPs were represented on a heat 
      map and a three-dimensional coordinate system based on the K (0) patterns, from 
      which they could be readily identified. Under optimal conditions, the limits of 
      detection (LODs) of the tested OPPs were evaluated to be 0.3-2.7 ng, and 
      satisfactory repeatability was demonstrated by the obtained relative standard 
      deviations (RSDs) of 4.8% to 14.7%. Finally, Chinese cabbage extract spiked with 
      dursban and malathion was detected by the proposed ion mobility spectrometer, 
      demonstrating its applicability for the simultaneous identification of coexisting 
      OPPs in real samples.
