Structure 2.2.10—Chromatography is a technique used to separate the components of a mixture based on their relative attractions involving intermolecular forces to mobile


Here are experiments our science specialists have selected to support this IB* topic.

Arson Analysis: Using Gas Chromatography

Experiment #15 from Forensic Chemistry Experiments

  • Create gas chromatograms for crime scene accelerant and known compounds.
  • Identify the components of the accelerant collected from the crime scene.

Liquid Chromatography

Experiment #18 from Advanced Chemistry with Vernier

In this experiment, you will

  • Conduct an isocratic, liquid-chromatographic separation.
  • Conduct a step gradient, liquid-chromatographic separation.
  • Complete the necessary measurements and calculations to evaluate the components of a mixture that have been separated by liquid chromatography.
