Multi-point imbibition band for mass spectrum identification

The utility model discloses a multi-point imbibition band for mass spectrum identification, which comprises an imbibition layer and a waterproof layer which are arranged from bottom to top, and the imbibition layer and the waterproof layer are attached into a whole; the liquid absorbing layer comprises a liquid absorbing material and is used for absorbing liquid in contact with the liquid absorbing material; the waterproof layer is used for preventing liquid in the liquid absorption layer from permeating to the upper surface of the liquid absorption belt. The liquid suction device is specially designed for liquid suction in microbial mass spectrum identification. During use, the liquid absorption belt is vertically moved to the upper surface of the multi-point target plate through the arranged horizontal pressing plate, so that an upper-layer solution in each point can be absorbed and discarded at one time. The capillary phenomenon is utilized, so that the liquid absorption process is uniform, stable and rapi
