![]() ![]() Similarly, the lower coil is filled with the black phase and the white phase is introduced from the tail end. ![]() The mobile phase (black) then travels rapidly through the coil, leaving a large volume of the stationary phase in the coil. In Figure 6B, the upper coil is filled with the white phase and the black phase is introduced from the head end. This equilibrium condition indicates that the white phase, if introduced at the tail, would move toward the head, and similarly the black phase introduced at the head would move toward the head. The coil at the top shows the bilateral hydrodynamic equilibrium where the white phase (head phase) occupies the head side and the black phase (tail phase) the tail side of the coil ( Figure 6A). This hydrodynamic behavior of the two phases can be effectively utilized for performing CCC as illustrated in Figure 6, where each coil is drawn as a straight tube. ![]()
