Abstract
Analysis of biological small molecules such as toxins, spores or cells is achieved by miniature mass spectrometer apparatus and apparatus attached thereto for vaporizing and ionizing a liquid sample fed into an evacuated vaporization chamber as an electrospray. The mass spectrometer apparatus includes: a collimation chamber, a repeller assembly, an internal ionization chamber, a mass filter and ion separation chamber, a drift space region, and a multi-channel ion detection array so as to permit the collection and analysis of ions formed over a wide mass range simultaneously. The vaporization chamber includes an output port adjacent the input to the collimation chamber so as to maximize the amount of vaporized material being fed into the mass spectrometer apparatus.
