Rf Values determine the solubility of a substance with respect to a certain solvent.
It also determines the affinity of the solute to the solvent
(greater Rf=greater affinity of solute to the solvent)

What is the difference between relative retention time and retention time?
the difference between retention time and retention factor is that the retention time is a quatitative value where`s the retention factor is a qualitative on.
What is the full name of Rf value?
Retention Factor Rf == Distance traveled / total distance
Why retention time vary during isocratic analysis?
Using isocratic retention parameters, the gradient elution retention time for several proteins has been calculated. The gradient retention time calculation is based on fitting the isocratic retention data to an equation of the form: log k′ = m log (1/[Ca2+]) + log K and on applying well-established principles of gradient elution. A good correlation between the observed and calculated retention times for several test proteins was obtained at various total gradient times and column flow-rates.Conversely, isocratic retention parameters characterizing protein retention can be calculated from gradient elution retention data. However, even with retention data of high quality, small errors are amplified by the log-log nature of the ion-exchange isocratic retention model employed.Based on the close correlation between predicted and observed gradient retention times, no evidence for protein denaturation resulting from immobilization of the protein at high initial k′ values at or near the column inlet was observed.
How is the retention factor measured in paper chromotography is related to pigmnet color in leaves?
Rf= distance travelled by pigment (cm)/distance travlled by solvent (cm)
What will be the effect of pH on retention time?
Retention time decrease with an increase in pH.

What is the Retention factor of caffeine?
it depends on the retention time, void time and reagents that you were used on your chromatograph.
What is the definition of a retention factor?
The retention factor of a particular material is the ratio of the distance the spot moved above the origin to the distance the solvent front moved above the origin.
Selectiv retention in communication implies?
Selective retention, in relating to the mind, is the process when people more accurately remember messages that are closer to their interests, values and beliefs.
