    Abstract: An inorganic mass spectrometer capable of measuring a relevant and large or the full mass spectral range simultaneously may include a suitable ion source (e.g., an ICP mass spectrometer with an ICP ion source), an ion transfer region, ion optics to separate ions out of a plasma beam, a Mattauch-Herzog type mass spectrometer with a set of charged particle beam optics to condition the ion beam before an entrance slit, and a solid state multi-channel detector substantially separated from ground potential and separated from the potential of the magnet.

    Abstract: A method for isotope measurement of charged species contained in a solution to be analyzed, particularly charged species having an isobaric interference, has the following consecutive steps: a) in the capillary of a capillary electrophoresis device, the solution to be analyzed is inserted contiguously between a terminating electrolyte and a leading electrolyte that, respectively, are placed after the inlet and before the outlet of the capillary and contain ions of the same charge but with mobility inferior and superior to those of said species; b) separating the species by using the capillary electrophoresis device according to the isotachophoresis mode; then c) in the continuity of the preceding step, performing an isotope measurement of the species detected in the form of a substantially constant amplitude signal by using an inductively coupled plasma mass spectrometer (ICPMS) connected by direct coupling with the capillary electrophoresis device.

    Abstract: The disclosed method and apparatus couple a membrane interface directly to a mass spectrometer at atmospheric pressure. The membrane may be in capillary or sheet form and allows the introduction of a liquid or gaseous sample to one side of the membrane while the other side of the membrane is bathed with a solution that can easily be used in an atmospheric pressure ionization source. Volatile molecules permeate through a suitable membrane such as poly-dimethyl silicone (PDMS), mix into the appropriate solvent, and are ionized. Because of the rules governing abstracts, this abstract should not be used in construing the claims.
