How do we calculate rf values
WebThe RF value calculator is a tool used in chromatography to calculate the retention factor or RF value of a compound. The retention factor is a measure of how strongly a compound interacts with the stationary phase in a chromatography system. It is defined as the ratio of the distance traveled by the solute (DSU) to the distance traveled by the ...
