The invention discloses a condensation chromatography column, which comprises a grinding mouth connector, an outer-layer glass pipe, a water inlet, an inner-layer glass pipe, a water outlet, sand cores, a teflon piston and a drainage pipe. The grinding mouth connector is connected with one end of the inner-layer glass pipe, and the other end of the inner-layer glass pipe is connected with the drainage pipe to form an integrated pipe; the first teflon piston is arranged on the drainage pipe; the sand cores are arranged on two end ports of the inner-layer glass pipe; the outer-layer glass pipe and the inner-layer glass pipe are connected to define a space; and the water inlet and the water outlet are formed in two ends of the outer-layer glass pipe. According to the double-layer condensation chromatography column provided by the invention, slightly cold circulating water flows into the outer-layer glass pipe, so that the volatilization of low-boiling-point eluents such as dichloromethane can be reduced, and the
