Abstract
A mass spectrometer device comprising an ion mobility separation device and a mass spectrometer that are coupled together. In order to achieve high efficiency, high throughput, and high sensitivity, the mass spectrometer is provided with: a first flow passagewaythrough which ions from an ion sourceare introduced into the mass spectrometerby passing through an ion mobility separation unita second flow passagewaythrough which the ions from the ion source are introduced into the mass spectrometer without passing through the ion mobility separation unit; and a switch means, such as shield unitsfor switching between the first flow passagewayand the second flow passageway
