Mission Assignment: CSI - Black Pen Investigation! Find out who has written a ransom note by using chromatography!

Discover how chromatography can be used to identify the source of black ink by analysing the different components that separate as the solvent moves through filter paper. This practical approach demonstrates how to set up and interpret chromatography experiments, which are invaluable in forensic science, food analysis, and chemical purification. Watch to learn how to distinguish between inks and solve real-world identification challenges through visual patterns and separation techniques.
