A sensitive and reliable method of analysis for ephedrine and its analogues was established by using GC and GC-MS. The columns used for both GC and GC-MS were HP-5, and the carrier gas was helium. NPD was used as the detector for GC. The urine sample was extracted with ether and submitted to GC. If positive, it was then submitted to GC-MS to identify its structure. The detection limits for ephedrine and its analogues are lower than 200 ng/ml urine. The recoveries are above 80%.
采用气相色谱法（GC）和气相色谱-质谱联用法（GC-MS）建立了一种灵敏可靠的麻黄碱及其类似物分析方法。GC和GC-MS所用的色谱柱均为HP-5，载气为氦气。GC采用氮磷检测器（NPD）。尿样用乙醚萃取后进行GC分析。若呈阳性，则进一步进行GC-MS分析以鉴定其结构。麻黄碱及其类似物的检测限低于200 ng/ml尿样。回收率高于80%。
