1引言爆炸是恐怖袭击的常用手段。对痕量爆炸残留物进行高效检测,从而准确判断炸药的成分和种类,能够为侦破案件提供重要的线索和证据[1,2]。近年来,毛细管电泳技术初步显示了其在爆炸物检验方面的巨大潜力[3～6]。本实验基于毛细管电泳间接紫外吸收检测[7,8]和胶束电动色谱[9],建立了痕量爆炸残余物的系统分析检验方法,通过对爆炸瞬间产生的痕量 1 Introduction Explosions are common means of terrorist attacks. The efficient detection of trace explosive residues, which can accurately determine the composition and type of explosives, can provide important clues and evidences for detecting cases [1,2]. In recent years, capillary electrophoresis has shown its initial potential for explosives testing [3-6]. This experiment based on the capillary electrophoresis indirect UV absorption detection [7,8] and micellar electrokinetic chromatography [9], established a systematic analysis of trace explosives residue testing methods, through the explosion of the moment of trace
