Abstract
In a liquid chromatograph mass spectrometer having an ionization interface capable of simultaneously performing ionization operations by ESI and APCI, a spray nozzlefor spraying a liquid sample given form a liquid chromatograph section as charged droplets, and a corona dischargerfor ionizing mobile phase solvent molecules are placed in the same ionization chamber. The same voltages are applied to both the spray nozzle and the corona discharger from a single high-voltage power supply. The electrical power's value of the heaterof the heated dry gas supplier for drying the charged droplets generated in the spray nozzleare set to be suitable for the ionization according to APCI. Consequently, the labor for the circuit design and the number of the parts are reduced. At the same time, the parameter setting items for the user are decreased, which leads to enhanced operability.
