Better Understanding Theoretical Knowledge through Laboratory Teaching: Taking “Gas Chromatography Experiment” as an Example

School of Chemistry and Molecular Engineering, East China University of Science and Technology, Shanghai 200237, P. R. China

Received Date: 30 June 2019

Instrumental analysis is a required course for the students of chemistry major. The basic concepts and principles involved in this course are abstract and hard to understand. In this paper, we take gas chromatography experiment as an example to help the students to understand the knowledge by studying the effects of important parameters including column temperature, carrier gas flow-rate, injection volume, and split ratio of capillary gas chromatography on the separation resolution. These experiments could help the students to improve their abilities of analyzing and solving problems and scientific research thinking as well.
