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 are introduced to a gas chromatography using a discovery-based approach. They are presented with a scenario/industrial application where their job is to verify that the company's mouthwash contains a specific percentage of...

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...

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...

Thin-layer and gas-liquid chromatography are introduced in an intelligible presentation. Paper chromatography is also listed as another type of chromatography, but it is not explained. If you are particular about appearances, there are...

Students analyze gas chromatograms and suggest various applications for gas chromatography.

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.

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Twelfth graders research physical and chemical methods used in authenticating paintings (e.g., ultraviolet fluorescence and spectroscopy, infrared spectroscopy and reflectography, X-ray diffraction, microscopy, pigment analysis, and gas...

Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.

Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.

Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...

This page uses diagrams and charts along with written text to explain gas chromatography.

An introduction and schematic of a gas chromatograph, with a link to pictures.

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

This lesson focuses on analyzing and identifying substances. Substances can be analyzed using a variety of methods including paper chromatography, gas chromatography and mass spectrometry. After reading about the different techniques,...

Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different...

This comprehensive interactive tutorial continues to explore the forensic science field. Learn how organic materials of evidence are analyzed and what the various types of chromatography are, especially why they are so important to this...
