本法叙述了生物体液中小量有机硷的快速检定方法。这种方法对于纸上层析法特别适宜。并列出了咖啡,咖啡因,可卡因、尼古丁等几种不同有机硷的一些试验结果。此法已进一步用于检定尿中或其他体液中可能遇到的不正常的有机硷,其浓度约为1P.P.M,这种方法简单并且仅需要小型的装置,同时在作者的实验室中已经广泛地试用三年了。这种方法实质上是两步提取,先用一种不混合的有机溶剂从尿中提取有机硷,然后将
This Act describes the rapid determination of small amounts of organic bases in biological fluids. This method is particularly suitable for paper chromatography. And lists some of the test results of several different organic bases such as coffee, caffeine, cocaine and nicotine. This method has been further used to test urine or other body fluids may encounter abnormal organic base at a concentration of about 1P.PM, this method is simple and requires only a small device, while in the author’s lab has been Try it for a wide range of three years. This method is essentially a two-step extraction in which the organic base is first extracted from the urine with a non-mixed organic solvent and then
