Abstract: In the teaching of instrument analysis experiment courses, some methods and principles of several instruments are quite complex and difficult to understand, making it difficult for many students to comprehend and understand them in a short period of time, resulting in poor teaching effectiveness. This article introduces some experiences and methods in the teaching process of instrument analysis experiment course. Combining numerical values with graph can make it more intuitive and quantitative in explaining abstract content, and enable students to grasp the principles of instruments quickly. Teaching practice has proven that this method can adapt to characteristics of instrument analysis experimental courses, improve teaching efficiency, and achieve good teaching results.

Key words: Instrument analysis, Teaching methods, Numerical-graph integration
