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.
