Chromatography Lab
Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places.
Oregon State
Using Paper Chromatography
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.

Lipstick Chromatography/Ink Chromatography
Junior crime scene investigators are instructed in two different chromatography exercises. For female suspects, they separate and compare lipstick pigments. For male suspects, they separate and compare ink samples. A data sheet is...

Mixtures and Solutions: Paper Chromatography Experiment
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...

Recognition and Classification of Mixtures
Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight...

Paper Chromatography K-12 Experiment
Students study chromatography and how they can distinguish between the different pigments in a color. In this chromatography instructional activity students separate a mixture of dyes in soluble ink then record the colors they see.
Curated OER
Chromatography
Learners conduct various experiments on chromatography. In this chemistry lesson, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.

The Conceptual Theory of Chromatography
Students 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 report on...
Curated OER
Ink Analysis and Thin Layer Chromatography
Learners explain the process of TLC. They identify at least three components of ink. They analyze data and make conclusions based on laboratory observations.
Curated OER
Introducing Chromatography
Students investigate chromatography. In this chromatography lesson plan, students investigate a lab set up for chromatography.
Curated OER
Paper Chromatography
Students participate in an experiment determining how to separate a mixture of dyes in water-soluble ink.
Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.

Leaf Chromatography
You can bring science alive for students with these lessons on leaf pigments.
Curated OER
Chromotography
In this chromatography worksheet, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.
