Abstract:

In order to improve students' theoretical level and practical ability, a comprehensive experiment, the determination of amino acids in Cerasus humilis fruit, was designed for instrumental analysis course. The sample analysis pretreatment process was introduced to construct a complete instrumental analysis process. Through the comparison of amino acid extraction methods and the exploration of solid phase extraction technology in the process of amino acid purification, students' theoretical knowledge and practical ability can be effectively fused and improved, and the scientific literacy and comprehensive thinking ability of students can thus be improved during the process of solving practical problems.

Key words: Comprehensive experiment, Instrumental analysis, Solid phase extraction, Amino acids analysis
