To calculate an Rf value divide the distance travelled by the component in other words the distance from the starting pencil line to the coloured spot -by the distance travelled.

. Stationary and Mobile Phases. Two pigments with the same Rf value are likely to be. How to calculate a Rf value.

Why is the rf. The solute migration value is compared by the solvent front migration value to calculate the Rf value which gives just a ratio number. What are the advantages of calculating.

Formula to Calculate the Rf Value. The rf for a particular chemical is the vertical distance traveled by a chemical from the place where it was originally spotted on the tlc plate divided by the length traveled. How to calculate rf values for an ink pen chromatography.

Visit dBm to dBW converter RF Calculator 6. Samples and then check the bed of protein and maker then you. How to Calculate RF Value Define Retardation Factor.

To calculate an Rf value divide the distance travelled by the component in other words the distance from the starting pencil line to the coloured spot -by the distance travelled. Also you can use the following image for finding more way and detail abou Rf calculation in SDS-PAGE. The Rf value can be used to calculate the molecular weight of the protein of interest.

Even if the mobile phase solvent is the same various compounds have varying R f values. The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper. This is represented by the R f value which stands for relative front or retardation factor.

Rf Distance traveled by the compound aDistance traveled by the solvent front b The Rf value is also called the ratio-to front.
