摘要
气相色谱法已广泛应用于医药、精细化工和食品行业。本文利用气相色谱法,考察并优化了影响二甲苯三种同分异构体分离的主要因素和条件。根据气相色谱实验教学内容,把气相色谱定性分析、实验条件优化和分离度计算这3个独立的知识点贯穿起来,设计了4学时实验。该实验操作简便,学生练习机会较多,提高了学生理论联系实际的能力。
Gas chromatography method is widely applied in medicine,fine chemicals and food industry.In this paper,gas chromatography method is used to investigate and optimize the main factors and conditions affecting the separation of three isomeric if xylene.Qualitative analysis of gas chromatography,optimization of experimental condition and calculation of resolution are connected according to the teaching of gas chromatography experiment and four hours experiment is designed.This experiment is easy to operate and students will have more opportunities to practice to enhance their ability of linking theory with practice.
