Chiral mesoporous materials have widely applications in chiral separation, asymmetric catalysis, and chiral sensing. Chiral order inorganic mesoporous silica (COIMS) is a kind of chiral materials with high order mesoporous structure not containing organic component. Here we report that a COIMS diluted with a polysiloxane OV-1701 was explored as a novel stationary phase for capillary gas chromatography. The COIMS was synthesized from D-phenylalanine chiral source, and its separation properties of the chiral column were investigated. Eight enantiomers including chiral alcohols, dialcohols, esters and amino acid derivative have been resolved on the coated capillary column. In addition, COIMS chiral column also exhibits good selectivity for the separations of linear alkanes and alcohols. This work indicates that the column has the advantages of high temperature resistance and short analysis time, so it has great potential to develop it as a chiral stationary phase at high temperature.
