摘　　要：目的建立疑似毒品中新型苯环己哌啶类麻醉活性物质氟胺酮的GC/MS检验分析方法。方法通过气相色谱质谱联用仪(GC/MS)对疑似毒品固体中氟胺酮进行检验研究,并对所获得的质谱图进行解析,推测氟胺酮电子轰击电离(EI)的碎裂途径。结果测得未知组分的(tR=12.03min)质谱特征碎片峰信息为m/z 164(基峰)、193、150、136、122和115等。经与氟胺酮标准物质的保留时间和质谱图比对,确定为氟胺酮成分。结论该方法简易可靠,适用于疑似毒品中氟胺酮成分的检验鉴定。Objective To establish a method for the new phencyclidine anesthetic active substance F-Ketamine in suspected drugs by(GC/MS)Method Gas chromatograph-mass spectrometer(GC/MS)was used to examine and study the F-Ketamine in the suspected drugs,and the obtained mass spectrum was analyzed to infer the fragmentation by EI.Results Mass spectral characteristic fragment peak information of the unknown component(tR=12.03 min)was measured as m/z 164(base peak),193,150,136,122,and 115.After comparison with the retention time and mass spectrum of the F-Ketamine standard substance,it was identified to be the F-Ketamine.Conclusions This method is simple and reliable,and is suitable for the identification of F-Ketamine in suspected drugs.
