传统仪器分析实验课程实验内容陈旧,学生积极性低,我院仪器分析实验教学中采用凝胶色谱测定纤维素分子量。介绍了凝胶色谱测定的基本原理和实验步骤,实验教学提高了学生实验兴趣和职业能力,效果良好。最后指出实验教学是一项长期艰巨的工作,需要不断地创新、总结和完善来适应社会发展的需求。 Traditional instrumental analysis experimental course experiment content is obsolete, student enthusiasm is low, our hospital instrumental analysis experiment teaching uses gel chromatography to measure cellulose molecular weight. The basic principles and experimental steps of gel chromatography were introduced. Experimental teaching improved students’ experimental interest and professional ability, and achieved good results. Lastly, it points out that experimental teaching is a long-term and arduous task and needs constant innovation, conclusion and improvement to meet the needs of social development.
