Three variables characterizing the mobile phase composition, pH, elution strength and ionic strength, have been studied in order to construct a three-dimensional semiempirical model for predicting retention times of dibasic substances. The solutes treated quantitatively include dibasic acids and bas
approximate movement of the plunger during packing is 40 mm. The diagram (Figure 1) is to scale, except for the O-rings, valves and tube fittings. Packing with this system wassatisfactoryexcept when we failed to add enough packing material to fill the column completely, or when the stirring bar fail
