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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
