介绍并评价了本科生二年级化学实验班的正相柱层析入门实验。该实验涉及亲核取代反应，产生反应物和一种产品的粗略混合物，这两种产品都颜色鲜艳，对比强烈，使用柱层析进行纯化时，产生了明显的视觉分离。一项学生调查显示，75.4%的学生(n=53，约占年级组的50%)同意或强烈同意实验对他们来说效果很好，88.7%的学生同意或强烈同意实验是愉快的。每个学生还在实验室接受了实用技能评估，年级组在这一评估中的平均得分为72.1%。
: An introductory normal phase column chromatography experiment is described and evaluated for second year undergraduate chemistry laboratory class. The experiment involves a nucleophilic substitution yielding a crude mixture of reactant and one product, both of which are brightly colored and contrasting, creating a clearly visual separation when purified using column chromatography. A student survey was conducted which showed that 75.4% of students ( n = 53, approximately 50% of year group) agreed or strongly agreed that the experiment worked well for them, and 88.7% agreed or strongly agreed that the experiment was enjoyable. Every student was also assessed in the lab on their practical technique, with the year group achieving an average of 72.1% in this assessment.
