Flashcards
Rf value
Rf value
A measure of how far a substance travels during chromatography, relative to the solvent front.
What does Rf value quantify?
What does Rf value quantify?
The distance traveled by a substance compared to the distance traveled by the solvent in chromatography.
Rf value range
Rf value range
The Rf value can range from 0 to 1, indicating how far a substance has moved relative to the solvent front.
Study Notes
Rf Value in Chromatography
- Rf value quantifies the distance traveled by a substance in a chromatogram relative to the distance traveled by the solvent front.
- Rf value equals the ratio of the distance traveled by the substance to the distance traveled by the solvent front.
- The range of Rf value is 0 to 1, where 0 indicates the substance did not move from the origin and 1 indicates the substance moved with the solvent front.
