Abstract: An isotope mass spectrometer including: an electron cyclotron resonance ion source, a front-end analysis device, a back-end analysis device and an ion detector; where the electron cyclotron resonance ion source is connected with the front-end analysis device, and is used for generating ion beams of multivalent charge states; the front-end analysis device is connected with the back-end analysis device, selects and separates the ion beams, and receives ion beams of constant, microscale and trace levels; the back-end analysis device is connected with the ion detector, and is used for eliminating a background of an isotope to be measured at an ultratrace level; and the ion detector is used for receiving ion beams of the ultratrace level, and carrying out energy measurement and separation on the ion beams of the ultratrace level, so as to obtain the isotope to be measured at the ultratrace level.
