METHOD AND APPARATUS FOR OPERATING AN ANALYTICAL MASS SPECTROMETER WITH A GETTER-ION PUMP
Patent
·
OSTI ID:4773424
A method and apparatus for connecting an ion pump to an analytical mass spectrometer are described which eliminate possible contamination due to the species selectiveness of the ion pump. The connection includes means for controlling the conductance of the spectrometer system so that the pump does not pump some species faster than others. (D.L.C.)
