- (i) Chromatography
- Chromatography is a technique used to separate the components present within a mixture. Chromatography separates substances by making use of differences in their polarity or molecular size.
- The details of any specific chromatographic method or experiment are not required. Depending on the type of chromatography used, the identity of a component can be indicated either by the distance it has travelled, or by the time it has taken to travel…

- Thin-layer chromatography
- Candidates should be familiar with thin-layer chromatography experimental procedure.
- Rf values can be calculated and under similar conditions a compound will always have the same Rf value within experimental error.
- Since a pure substance will show up as only one spot on the chromatogram, TLC can be used to assess the purity of a product prepared in the lab.
