An introduction to various forms of chromatography: thin layer, column, high performance liquid (HPLC), gas-liquid and paper.
- A. Introducing Chromatography: Thin Layer Chromatography
- This page is an introduction to chromatography using thin layer chromatography as an example. Although if you are a beginner you may be more familiar with paper chromatography, thin layer chromatography is equally easy to describe and more straightforward to explain.
- B. Column Chromatography
- This page shows how the same principles used in thin layer chromatography can be applied on a larger scale to separate mixtures in column chromatography. Column chromatography is often used to purify compounds made in the lab.
- C. High Performance Liquid Chromatography (HPLC)
- High performance liquid chromatography is a powerful tool in analysis. This page looks at how it is carried out and shows how it uses the same principles as in thin layer chromatography and column chromatography.
- E. Paper Chromatography
- This page is an introduction to paper chromatography - including two way chromatography.
