摘要:Micro-analysis of ethyl ether in forensic chemistry was investigated. Gas-liquid chromatography was employed for detection of ethyl ether from biological fluids. As pre-treatment, ethyl ether was extacted with n-propyl- or butyl-acetate. Cyclohexane was conveniently used as an internal standard. It was found that the method was available for quantitative analysis of ethyl ether in biological fluids. Micro diffusion method and Widmark's method were also investigated for quantitative determination of ethyl ether, and it was found that both, especially the later, gave good results. Several forensic applications of these methods were also discribed.
