RF Value Calculator

Enter the distance traveled by the solute and the distance traveled by the solvent into the calculator to determine the RF value.

RF Value Formula

The following formula is used to calculate a RF Value.

Rf = DSU / DSV

  • Where Rf is the retention factor
  • DSU is the distance traveled by the solute
  • DSV is the distance traveled by the solvent

RF Value Definition

An RF value is a ratio of the distance of travel of a solute compared to a solvent.

RF Value Example

How to calculate an RF value?

  1. First, determine the distance of the solute.

    Determine the distance travelled by the solute.

  2. Next, determine the distance of the solvent.

    Determine the distance travelled by the solvent.

  3. Finally, calculate RF value.

    Calculate RF value using the formula above.


FAQ

What is an Rf value?

Rf value stands for retention factor. It is a ratio of the distance of travel of a solute compared to a solvent.

What is Rf value used for?

Rf values are used to compare the distance of particles travelling within a solution that can then be used to identify the components of the solution based on the results.
