The invention discloses a
dynamic monitoring chromatographic column with a built-in
phased array ultrasonic detection and
ultraviolet detection module capable of automatically ascending and descending, which comprises a
chromatographic column body filled with a filler, a hollow short shaft is arranged in the
chromatographic column body, a long shaft is arranged in the hollow short shaft, the long shaft extends out of the hollow short shaft into the resin filler, and the long shaft is connected with the chromatographic column body. A liquid inlet
distributor is mounted on the outer surface of the hollow short shaft,
phased array ultrasonic detectors are mounted on the liquid inlet
distributor, a plurality of flexible
phased array ultrasonic detectors are uniformly arranged on the outer surface of the chromatographic column body along the height direction of the chromatographic column body, an eluent
ultraviolet (UV) detection module is arranged at the end part of the long shaft, and an automatic lifting
ultrasonic detection module is arranged at the top end of the chromatographic column body. According to the invention, the filler distribution in the axial direction and the radial direction of the chromatographic column is monitored in real time, and a phased array
ultrasonic imaging technology and a fusion technology of axial imaging along the chromatographic column and radial imaging at different axial heights are combined to superpose the three-dimensional imaging of the filler in the whole chromatographic column, so that the filling uniformity of the chromatographic filler is more accurately judged.
