1. mass spectrometer multichannel ion source, comprise high voltage source, nozzle and sample disc, it is characterized in that, also comprise at least two passages and two nozzles, its first passage is made up of first capillary and a discharge electrode that is placed in one, the termination of discharge electrode extends to outside first capillary to sample ionization district direction, and imports chemi-ionization reagent in this first capillary, and the reagent ion that is obtained by the corona discharge of discharge electrode enters the sample ionization district;

  • Second channel is made up of sheath gas capillary and the sample nozzle that is placed in one, and the jet of sample nozzle extends to outside the sheath gas capillary to sample ionization district direction, and this sheath gas capillary has carrier gas, be written into sample or auxiliary reagent in the sample nozzle, add and depress that second channel forms sample or reagent flows to into the sample ionization district;

    Described sample or reagent stream form sample ions with the reagent ion collision and are introduced in the mass spectrometric inlet capillary in the sample ionization district.
