Abstract
With rotating and translating a rotation-translation drum installed in a vacuum chamber of a mass spectrometry interface to constitute a mass spectro-meter, a liquid sample incorporating a dissolved substance to be analyzed in its mass is emitted for the drum from a sample supplying nozzle of the mass spectrometry interface, and the dissolved substance is isolated as a spiral filament on the drum. Then, a laser beam is irradiated onto the filament from a laser source via a laser beam inlet situated at the vacuum chamber and thereby, the dissolved substance is ionized without exposing to the air.
