On-site Rapid Analysis of Hydroxylimine Based on Surface Acoustic Wave Gas Chromatography

目的对羟亚胺制毒现场收集的残留物含有的挥发性和半挥发性成分进行分析。方法使用声表面波气相色谱仪对羟亚胺残留物进行检测,并对相关的标准物质进行测定,再结合使用气相色谱-质谱的方法对测定结果进行验证。结果声表面波气相色谱和气相色谱-质谱法分析结果显示,羟亚胺残留物中含有主成分羟亚胺,并含有合成羟亚胺的原料2-氯苯甲腈、环戊酮等。结论声表面波气相色谱仪能够实现对羟亚胺残留物中挥发性和半挥发性成分的现场快速分析。本文提出的方法,具有待检样品无需前处理、分析速度快、能够实现现场检测等优点,为易制毒化学品及毒品的快速检测提供了高效、便捷的新途径。

Objective To analyze the volatile and semi-volatile components contained in the residual hydroxylimine manufacture collected on the scene.Methods The hydroxylimine residues were collected,then detected by gas chromatography with surface acoustic wave(GC-SAW),with the related standard materials being determined.The gas chromatography-mass spectrometry(GC-MS)was applied to verify the above determination.Results Both GC-SAW and GC-MS showed that the hydroxylimine residues contains the main component of hydroxylimine plus the raw materials of the synthesized hydroxylamine:2-chlorobenzonitrile,cyclopentanone and the like.Conclusions GC-SAW can achieve accurate and rapid qualitative analysis of hydroxylimine residues.The method proposed here has the advantages of no pretreatment,fast analysis,and the ability to detect on site,thus bringing forward a new avenue for the rapid detection of precursor chemicals and drugs.
