Thin Layer Chromatography Rf Values Table Decorative Journals from nev-logy.blogspot.com
The rf value of a compound is equal to the distance t. Tlc plates are generally made of aluminum coated by the stationary phase, and can be cut with scissors. You may try with hptlc.
Calculating Radiochemical Purity Can Now Be Determined;
Rf in tlc measure in simple way by measuring the distance travelled by analyte/solvent front measured from where the analyte applied. A convenient way for chemists to report the results of a tlc plate in lab notebooks is through a retention factor , 2 or r f value, which quantitates a compound's movement. Hence, it is theoretically possible that a compound with rf.
