The components are arranged on a plane nonconductive substrate (1), having an energy filter (k) for the ions, the energy filter being embodied as a 90° sector, is constructed in completely planar fashion. The ionization chamber (b), the electrodes (g, h, j, m) for accelerating the electrons and ions, the detector (l) for the ions and the energy filter (k) are produced by a single step of photolithography and etching of a doped semiconductor die (6) applied to the substrate (1) and the wiring (2) and the abovementioned parts are covered by a second flat nonconductive substrate (7).

    Abstract: Novel and significantly simplified procedures for fabrication of fully integrated nanoelectrospray emitters have been described. For nanofabricated monolithic multinozzle emitters (NM2 emitters), a bottom up approach using silicon nanowires on a silicon sliver is used. For microfabricated monolithic multinozzle emitters (M3 emitters), a top down approach using MEMS techniques on silicon wafers is used. The emitters have performance comparable to that of commercially-available silica capillary emitters for nanoelectrospray mass spectrometry.

    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.

    Abstract: A method of aligning sets of cylindrical electrodes in the geometry of a miniature quadrupole electrostatic lens, which can act as a mass filter in a quadrupole mass spectrometer is provided. The electrodes are mounted in pairs on microfabricated supports, which are formed from conducting parts on an insulating substrate. Complete segmentation of the conducting parts provides low capacitative coupling between co-planar cylindrical electrodes, and allows incorporation of a Brubaker prefilter to improve sensitivity at a given mass resolution. A complete quadrupole is constructed from two such supports, which are spaced apart by further conducting spacers. The spacers are continued around the electrodes to provide a conducting screen.
