Chromatography is the oldest documented technique to separate chemical substances. In this activity, students will perform paper chromatography on three individual dyes and a mixture of dyes to determine if all three dyes are in in the mixture. They will understand not only the components of a chromatography system, but also why different substances move at different rates within the system.
