What this topic asks you to be able to do
- describe and understand these terms: (a) stationary phase, a non-polar liquid with a high boiling point held on a solid support (b) mobile phase, which is a gas that does not react (c) retention time
- interpret gas /liquid chromatograms so as to express the makeup of a mixture as percentages
- explain retention times by considering how each substance interacts with the stationary phase
