摘　　要：高效液相色谱(HPLC)是重要的仪器分析方法之一,然而大学仪器分析课程对于其固定相仅是粗略讲解,不能使学生将van Deemter方程理论知识与色谱柱固定相实际结构切实联系起来。本文介绍了一类新型核壳固定相,并从核壳型固定相的发展沿革、分离原理、结构优势几个方面分析了其教学应用。便于学生理解van Deemter方程应用并激发学生的学习兴趣。High performance liquid chromatography(HPLC)is one of the important instrument analysis methods.However,in university-level instrumental analysis course,the stationary phase is often explained only briefly,which prevents students from effectively linking the theoretical concepts of the van Deemter equation with the practical structure of chromatographic stationary phases.This article introduces a new type of stationary phase—core-shell stationary phase—and analyzes its application from the development history,separation principle,and structural advantages.Not only does it facilitate students to understand the application of the van Deemter equation,but it can also stimulate their learning interest and exploratory spirit.
