  5. 5. Organosiloxanes containing cyano groups for capillary chromatography

    Författare :Karin Markides; Stockholms universitet; []

    Sammanfattning : Methods have been developed for the preparation of capillary columns coated with organosiloxanes containing cyano groups. A procedure was developed for surface modification of the capillary tubing, by means of high temperature silylation. Such a modification gives deactivation and creates a surface suitable for coating with cyanosilicones. LÄS MER
