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?

**First, determine the distance of the solute.**Determine the distance travelled by the solute.

**Next, determine the distance of the solvent.**Determine the distance travelled by the solvent.

**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.
