Guided Notes
3 key concepts
- 1
In paper chromatography, a mixture of substances is applied to a filter paper called the stationary phase, while a pure solvent moves over it, called the mobile phase.
- 2
The RF value is calculated using the formula: RF = distance traveled by the component from the original line divided by distance traveled by the solvent from the original line.
- 3
To prepare the chromatography paper, a line should be drawn with a pencil 2 cm from the end, and the ink spot should be allowed to dry completely between applications.
