Abstract
The quantitative accuracy of analysis is improved without reducing the dynamic range for measurement of concentrations by performing stable ionization through electrospray or the like which repeats sampling and ionization using a movable probe electrode.A voltage is applied from a high-voltage power source 4 to a sample transport electrode 7 having a plurality of probe electrodes 1 and a driving section 3 drives the sample transport electrode 7 to rotate. The plurality of probe electrodes 1, to which a sample solution 5 is adhered, are sequentially transported to an inlet 21 of a mass spectrometer 20, thus electrospray ionization is continuously performed.
