The application discloses a
solid-phase extraction instrument capable of collecting waste liquid, and belongs to the technical field of
solid-phase extraction instruments.The
solid-phase extraction instrument comprises a base and a support vertically fixed on the upper surface of the base, a plurality of extraction columns are installed on the support at equal intervals, a guide rail frame is fixedly installed on the support, a guide sliding groove is formed in the guide rail frame, a guide sliding block is slidably installed in the guide sliding groove, and a composite moving seat is installed on the guide sliding block; the composite moving seat comprises a bottom disc sliding along the direction of the guide rail frame, a
rotating disc is rotatably installed above the bottom disc, a plurality of circular grooves are formed in the
rotating disc at equal intervals along the axial direction, and a waste
liquid tank is clamped and installed in the circular groove; a liquid
discharge port is installed through the extraction column, an intelligent filtering mechanism for sensing and filtering the blockage in the liquid
discharge port is arranged between the waste
liquid tank and the extraction column, and the solid-phase extraction instrument can classify and collect waste liquid, can sense the blockage state of waste liquid
discharge during the collection of waste liquid, can filter the slightly blocked filler particles, and can assist in the smooth collection of waste liquid.
