Apparatus for high spatial resolution laser desorption ionization imaging mass analysis

摘要

Disclosed herein is an apparatus for high spatial resolution laser desorption ionization mass analysis. A main body is installed in an ion inlet of a mass analyzer. A reflector reflects a laser beam frontward of the main body. A sub-mirror diffuses the laser beam, reflected by the reflector, towards the main body. A main mirror condenses the laser beam, diffused by the sub-mirror, to front outside of the main body to ionize a specimen placed frontward. A hollow capillary is provided to introduce ions generated by condensation of the main mirror into the mass analyzer.
