鉴于COVID-19疫情，本集团在家中使用简化的柱层析装置进行墨水标记和食用色素的原色分离，以实现课程的教育成果。虚拟课堂教学，为学生参加了有机技术实验室课程，允许以类似于面对面的经验的方式了解色谱的基本原理。用于进行实验的材料在家里很容易获得，或者在药店或杂货店很容易找到。观察到各种各样的结果，其中80%的学生实现了至少两种原色的分离。
In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the Organic Techniques Laboratory course, allows the understanding of the basic principles of chromatography in a way similar to that in the face-to-face experience. The materials proposed for conducting the experiment are readily available at home or easily found in a drugstore or in a grocery store. A wide variety of results were observed where the separation of at least two primary colors was achieved by 80% of the students.
