The application of field tests and chromatography to the detection of cocaine and some other local anesthetics that have been used to adulterate cocaine is described. Initial screening of samples by field tests, followed by concurrent TLC and GC, enables rapid identification of these compounds to be achieved. In particular, the use of flow-programmed GC shortens the time for analysis compared with conventional GC and requires negligible equilibration time between consecutive runs [12]. The method gives reliable quantitative data.
描述了现场测试和色谱法在检测可卡因以及其他一些曾被用于掺假可卡因的局部麻醉剂中的应用。通过现场测试对样品进行初步筛选，随后同时进行薄层色谱法（TLC）和气相色谱法（GC），能够快速鉴定这些化合物。特别是，与传统气相色谱法相比，采用程序变流气相色谱法缩短了分析时间，并且连续运行之间所需的平衡时间可忽略不计[12]。该方法能提供可靠的定量数据。
