The invention relates to an analytical device and an analytical method for quinine concentration based on surface acoustic wave in series with a resonator biological tongue. The invention solves a problem of high cost due to usage of a concentration analyzer. The device comprises an acquisition workbench, an acquisition unit, a transition unit and a processing unit. The acquisition workbench comprises a base body, the base body is provided with a disc, the disc is provided with multiple liquid storage chambers, the bottom at one side of the disc is provided with a liquid dropping chamber, the bottom of the liquid dropping chamber is provided with a liquid dropping head, a base body below the liquid dropping head is provided with a placing groove. The acquisition unit comprises a cell plate electrode and a SAW resonator (surface acoustic wave resonator), the cell plate electrode is placed in a placing groove, the SAW resonator and the transition unit are connected, and the transition unit and the processing unit are connected. The invention has the advantages of simple structure, low making cost, convenient and fast operation, reduced operation personnel workload and reduced time, and concentrations of a plurality of solutions can be automatically detected by using the device. The detection process is convenient and fast, and the precision is high.
