ABSTRACT:
The present invention provides a column for a liquid chromatograph having a honeycomb substrate including holes through which a sample flows and a separation phase filled in the holes. The separation phase is a porous bone structure composed of an inorganic material having open pores formed therein, and the porous bone structure is generated by a sol-gel transition process accompanied by a phase transition.
