摘要：

The use of pure methanol as a separation medium for capillary electrophoresis (CE) has made possible the separation of non-ionic polyethers and the determination of their complexation constants with an electrolyte cation. The developed technique has proved to be efficient for the evaluation and detection of weak interactions (e.g., the interaction of benzo-12-crown-4 with various cations can be detected). This is a good example showing that the use of non-aqueous solvents in CE has allowed the utilization of interactions that hardly take place in water.
