Homochiral metal-organic frameworks（HMOFs） have special properties, such as high surface area, fasci- nating structures and excellent chemical and thermal stability and they have broad application prospects. In this work, we reported the use of HMOF Co-L-GG（L-GG, dipeptide H-Gly-L-Glu） as the stationary phase for separating race- mates m gas chromatography. Co-L-GG coated fused silica capillary colunm（10 m×250 μm i.d.） was prepared via a dynamic coating method. Thirty racemmes belonging to different classes of organic compounds were resolved in- cluding halohydrocarbons, ketones, esters, ethers, organic acids, epoxyalkanes, alcohols and sulfoxides. When com- pared with the previously reported chiral MOFs-coated capillary colurnlls, the Co-L-GG coated column exhibited broader chiral resolution ability towards chiral compounds.
