Abstract:
1. Apparatus for analyzing solid particles of an input sample of chemical or biological material, comprising: apparatus for converting solid particles of an input sample of chemical or biological materials into a vapor; mass spectrometer apparatus fabricated on a semiconductor chip connected to an output port of said converting apparatus for receiving said vapor therefrom and wherein the spectrometer apparatus includes; a collimation chamber located adjacent said output port and having at least one vacuum pumping inlet for evacuating and drawing vapor of the sample into the collimation chamber; a vacuum pump assembly for drawing ionized vapor into and conveying the vapor through the mass spectrometer; a repeller assembly located adjacent the collimation chamber; an ionization chamber located adjacent the repeller assembly for ionizing the vapor being fed thereto from the collimation chamber; an ion optics chamber located adjacent the ionization chamber; at least one evacuated mass filter and ion separation chamber located adjacent the ion optics chamber; a drift space region adjacent the mass filter and ion separation chamber; means for generating an electromagnetic field in the mass filter and ion separation chamber for separating ions therein by their respective mass/charge ratio; and a detector array located adjacent the drift space region for detecting ions separated in the mass filter and an ion separation chamber and traveling through the drift space region.
