介绍了在本科生分析化学实验室进行的离子色谱学实验。学生们以小组形式工作，负责识别现实世界中感兴趣的系统，并制定调查该系统的策略。学生将获得关于色谱学的具体技能和知识，以及更一般的分析技能，包括样品制备、系统校准、检测下限的确定和数据分析。给出了学生在课堂上做的两个具体实验实例：染发剂中铅的测定和橙汁中阴离子的测定。
An experiment using ion chromatography in an undergraduate analytical chemistry laboratory is described. The students, working in small groups, are responsible for identifying a real-world system of interest and for developing a strategy to investigate that system. The students gain specific skills and knowledge about chromatography as well as more general analytical skills including sample preparation, system calibration, determination of detection limits, and data analysis. Two specific examples of experiments done by students in the class are presented: the determination of lead in hair dye and the determination of anions in orange juice.
