Exploring Thin-Layer and Column Chromatography Fundamentals via Experiential Learning with Simple and Affordable Materials

The teaching of chromatography allows students to understand the fundamental principles of mixture separation and become familiar with organic chemistry concepts. However, in educational environments with limited resources, its implementation can be challenging due to the lack of specialized equipment and materials, or the impossibility of attending laboratories (as was the case during the COVID-19 pandemic). To address this, an alternative approach was developed that uses simple and low-cost materials to conduct chromatography experiments in the laboratory or at home.
