Light hydrocarbon analysis has applied extensively in the petroleum ge- ochemistry in foreign countries.This paper gives a brief presentation on the techniques in the analysis of C_2—C_9 light hydrocarbons.This technique is developed on the basis of the Schaefer method (FRG) with the addition of a hydrogen extraction device to a conventional gas chromatography.This is a well developed technique. This paper demonstrates the application of the data from light hydroca- rbon analysis:the abundance of adsorbed hydrocarbons on the rocks can be determined directly,and the source rocks can be evaluated in terms of the hydrocarbon content and composition,and some straight forward parameters for exploration petroleum geology are thus provided (this paper emphasized the easy and rapid characteristics of this method,and therefore,it is wort- hwhile to generalize such a technique).

A rapid spectrophotometric method based on FIA for the content uniformity test of atropine sulfate tablets has been developed. By means of the self-designed FIA system with an on-line extraction device, many difficulties resulting from extraction, such as slow analytical rate, environmental pollution, poor reproducibility, etc, were overcome, and the routine procedure of the official content uniformity test was tremendously simplified. Results obtained with the proposed method agree well with those obtained with the official test. Furthermore, the proposed method attained a sampling rate of 60 samples per hour, a recovery of 100.0%, a relative standard deviation of 0.7%, and a detection limit of 0.24μg/ml. Uniform design proves effective to optimize complex FIA conditions, and FIA promises a new approach to test the content uniformity of pharmaceutical tablets.

本文根据流动注射分析(flow injection analysis,FIA)的基本原理,建立了硫酸阿托品片含量均匀度检查的FIA在线萃取分光光度法。本文不仅简化了该片剂含量均匀度检查法(药典法)的分析过程,包括传统的萃取.分离,而且解决了该法分析速度慢、污染环境、重现性差等问题。本法与药典法所得结果一致,分析速度为60样/h,回收率为100.0%,相对标准差为0.7%,最低检测浓度为0.24μg/ml。所用FIA装置的流路设计具有通用性。分析条件的优化用均匀设计法进行,简便而有效。可以预期,FIA将为快速、准确地测定片剂含量均匀度提供一条新途径。

In this paper, a non-isothermal extraction process was proposed. And an extraction device has been designed. Extraction experiments have been made for DMF-heptane-toluene, DMF-hexanetoluene and DMF-water-hexane-toluene systems. The experimental results showed that the separation efficiency of the non-isothermal extraction process is 36%~57% higher than that of the ordinary isothermal extraction at the same conditions.
