Oh, chromatography test paper can bring to calculate the Rf has value Rf (Rate of flow) is the identity of substance. Depending on the type of solvent and adsorbent. So, tell the Rf of each species must tell the kind of solvent.Rf can be calculated by formula
.The Rf) = the distance of mobile / distance mobile solvent substances would be the Rf different. Therefore we can use value. Rf used in the analysis of substances, namely.Rf. Due to solvent is moving faster than the substance to separate the Rf less than one always 1 always if used solvent and the same adsorbents and valuable. Rf rate may assume that such compounds is the same.
