## Abstract The influence of different polysiloxane solvents on the efficiency and stereoselectivity of columns coated with mixtures of heptakis (2,3‐di‐__O__‐acetyl‐6‐__O__‐__tert__‐butyldimethylsilyl)‐β‐cyclodextrin and the polysiloxanes was investigated. Generally, the enantioselectivity increas
