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...

Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Students research the mechanics of liquid chromatography. For this technology lesson, students calculate the concentration of unknown samples. They write a report about their research and lab results.

Students 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 components of a...

Advanced techniques for the lab use of chromatography are detailed here and your students will learn the specifics of separating molecules using a staionary and mobile medium. Diagrams of the equipment used and some facts about how...

Wow! Expose your chemistry class to every method of separating mixtures by showing this slide show. Learners will view diagrams and graphic organizers that support notes about filtration, chromatography, distillation, centrifugation, and...

Students become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

High schoolers conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab...

Students conduct various experiments on chromatography. In this chemistry lesson plan, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.

Students research types of chromatography and complete chromatography experiments.

Students separate food coloring using liquid chromatography. In this chemistry lesson, students explain the effects of different solvents on the rate of separation.

Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.

Students determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Students identify the different components of a given sample using chromatography. In this chemistry lesson, students compare paper and column chromatography. They collect data and construct data tables.

Students identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.

What exactly goes into the medications people take every day? Scholars learn about the chemistry of medications in the second of a four-part series on Pharmacology. Over the course of two weeks, class members complete seven experiments,...
