✦ Synopsis


A miniaturized continuous gradient elution system with variable gradient profile was designed. A retention time reproducibility below 1% was achieved. The system was applied to the separation of phenolic compounds with a wide range of polarities.

One method of fractionating a density gradient after centrifugation is to puncture the bottom of the cent~fuge tube and then collect fractions of equal number of drops of gradient material. This method has its disadvantages. Occasionally air bubbles are introduced into the gradient
