A new type of capillary gas chromatographic stationary phase containing OH-dibenzo-14-crown-4 (OH-DB14C4) was fabricated by the sol-gel process and coated onto the inner walls of a fused silica capillary. Multiple preparation steps in conventional column technology were avoided. The column demonstrates high column efficiency (>
