How to Calculate RF Values? - Ask.com.

The ratio obtained by dividing the distance moved by the solvent front into the distance moved by the spot is called the retention factor value, Rf.
If the solvent front reaches the top of the paper you can't really know the distance traveled by the solvent (because there's no more stationary.
If the solvent front moves so fast as to travel off the paper, then you will not be able to calculate Rf values. These values are the distance.
distance moved by solvent front. It helps to write down the formula - that way you can easily see what information you already have -and then what you need.
Rf = distance moved by the spot of the substance / distance moved by the solvent front. Rf is fixed for a particualr component given a particualr solvent.

distance moved by solvent front

Chromatography activity - excelsoft - Learnpremium - Science.
The Rf value is the ratio of the distance shifted by the solute and the distance moved by the solvent (referred to as the Solvent front) alongside the paper where.

As it flows, the solutes dissolve within the moving solvent and are carried. usually until the solvent front is a predetermined distance from the top of the strip.

To answer the 2nd part, yes, Rf values are determined by divided the distance that the compound moved by the distance that the solvent front.
To calculate the RF values, it is taken from the ratio of the distance moved by the . chromatogram flat on a table and trace the position of the "solvent front" with a.
