ABSTRACT:
A mass spectroscope includes a mass analysis device having a surface provided with metallic members capable of exciting plasmons when irradiated by laser light, the mass analysis device allowing an analyte to be attached to the surface, a light radiation unit for irradiating the surface of the mass analysis device with laser light to ionize the analyte attached to the surface and desorb the analyte from the surface, and a detection unit for detecting a mass of the analyte ionized and desorbed from the surface of the mass analysis device from a time of flight of the analyte. The light radiation unit includes a polarization adjusting mechanism for adjusting a polarization direction of the laser light.
