| 英文摘要 | this paper introduces a simple method for selective and sensitive detection of black powder by adding chlorinated hydrocarbons in the drift gas instead of changing the structure of conventional ion mobility spectrometer (ims). the function of chloride modifiers was to substitute cl-(h2o)(n) for o-2- (h2o)(n) in the drift region so as to avoid the overlap between o-2(-) (h2o)(n) and sulfur ion peaks. among ch2cl2, chcl3 and ccl4, ccl4 was chosen as the modifier due to the best peak-to-peak resolution and stability towards the fluctuation of modifier concentration. with 1.4 ppm ccl4 as the modifier, the minimum detectable quantity of 0.1 ng for sulfur was achieved. moreover, this method showed the ability for detection of common explosives at sub-nanogram level, such as black powder (bp), ammonium nitrate fuel oil (anfo), 2,4,6-trinitrotoluene (tnt), and pentaerythritol tetranitrate (petn). in summary, this method requiring no configuration modification has high sensitivity and selectivity, and consumes trace amount of modifier. and these characteristics make it easy to be adopted in current deployed ims to detect black powder explosives.
