Introducing Chromatography
Young scholars investigate chromatography. In this chromatography lesson plan, students investigate a lab set up for chromatography.
Curated OER
Separation of Unknowns in a Liquid
Students identify the different components of a given sample using chromatography. In this chemistry activity, students compare paper and column chromatography. They collect data and construct data tables.
