Analysis device and method

The invention relates to an analysis device. The analysis device comprises a vacuum cavity, an electrode group, an ion transmission unit, a quality analysis unit and a control unit. The analysis device is characterized in that at least two ionization sources are arranged in the vacuum cavity; the analysis device also comprises a partitioning unit; the partitioning unit and each ionization source are correspondingly arranged between the corresponding ionization source and the electrode group to realize connection and disconnection of ions generated by corresponding ionization sources and vacuum; and the control unit controls the application of voltage on the electrode group and a partitioning mode of the partitioning unit so as to realize the effect that the ions generated by the corresponding ionization sources under different working modes of the ionization sources pass through the partitioning unit, then pass through the electrode group and the ion transmission unit in sequence and further enter the quality analysis unit to carry out detection. The invention also provides an analysis method. The analysis device and method have the advantages of wide detection range and convenience in switching among different working modes and the like.
