Novel chromatographic column

The utility model discloses a novel chromatographic column and belongs to the technical field of chromatographic columns. The chromatographic column structurally comprises a chromatographic column body, a light-transmitting tube and an ultraviolet lamp, the light-transmitting tube is used for flowing of a fluid to be subjected to chromatography, the ultraviolet lamp is used for irradiating the fluid to be subjected to chromatography in the light-transmitting tube, a feeding port and a discharging port are formed in the two ends of the chromatographic column body, and the light-transmitting tube is communicated with the feeding port and/or the discharging port; the light-transmitting tube is a spiral tube; the device further comprises an ultraviolet lamp box arranged at the feeding port and/or the discharging port, and the ultraviolet lamp box is arranged outside the space defined by the spiral pipe of the light-transmitting pipe and/or in the space defined by the spiral pipe. According to the novel chromatogr
