Can Chromatography Separate A Pigment?

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Students use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects match the...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Young scholars participate in a three-part lab in which they investigate plant pigments. Part I is designed to teach basic laboratory techniques of column chromatography, in Part II students design an experiment to separate the...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion questions.

Students use chromatography to separate substances in Kool-Aid, Crayola markers and leaves. In this chromatography lesson plan, students make chromatograms to separate substances in a mixture through absorption. Students find the Rf...

High schoolers perform paper chromatography to determine pigments in plants. In this paper chromatography lesson plan, students isolate leaf pigments, prepare a chromatogram and place their chromatogram in a solvent to separate the...

In this leaf chromatography worksheet, young scholars separate the pigments of a leaf using paper chromatography. They answer 4 questions about their results and draw the colors they observe on their chromatogram from the leaf.

Explains the distinction between the two main types of chromatography - analytical and preparative - and describes eleven chromatography techniques.
