摘要： 针对化学测量学与技术专业的培养目标，在本科实验教学中引入自搭建离子色谱仪实验课程，学生通过亲自搭建和调试仪器，加深对离子色谱仪器原理及构造的理解，训练学生的实践能力和创新思维。实验中利用商品化的配件和自加工的零件组装搭建具有完整功能的离子色谱仪，完成仪器的参数调试和性能测试，并利用自搭建的仪器测定自来水、湖水和饮料等实际水样中阴离子的含量，取得良好的教学效果。本实验设计以教学离子色谱仪搭建为例，展示实验仪器的设计思路和实现过程，让更多老师和同学加入仪器设计和新方法开发的队伍中。

Abstract: To align with the training objectives of the Chemical Metrology and Technology major, an experimental course on self-assembling ion chromatography instruments has been integrated into undergraduate laboratory teaching. By engaging in the hands-on assembly and optimization of these instruments, students deepen their understanding of ion chromatography principles and structures, enhancing their practical skills and innovative thinking. The experiment utilizes commercial components alongside custom-made parts to construct a fully functional ion chromatography system, calibrate its parameters, and evaluate its performance. Additionally, it analyzes anion concentrations in real water samples such as tap water, lake water, and beverages, yielding positive educational outcomes. This experimental design exemplifies the assembly of ion chromatography instruments, showcasing the design concepts and implementation processes involved, with the aim of inspiring more educators and students to engage in instrument design and the development of new methodologies.
