Abstract
A method for the immobilization of Chirasil-Val has been studied based on the cross-linking which takes place between terminal silanols of C hirasil-Val and polyfunctional silanes. A leached, dehydrated and tetr amethoxysilane-treated glass capillary coated with silanol terminated Chirasil-Val containing 5 % tetraacetoxysilane as a cross-linking agen t showed a maximum extractability of 15 % without any loss of chiralit y.
