Abstract: An ion trap mass analyzer includes an elongated tunnel that has a wall, a longitudinal axis and an inner space. The wall includes a substrate and conductor trace patterns. There is also a variable electric potential means for providing electric potentials which is connected to the conductor trace patterns. The conductor trace patterns and the variable electric potential means provide a variable electric field within the inner space of the tunnel for transferring, storing, and analyzing ions.

Abstract: There is a method of manufacturing organic thin film devices comprising the steps of dissolving an organic material in a first solvent, thereby providing a first solution; dissolving an inorganic salt in a second solvent, thereby providing a second solution; blending the first solution with the second solution, thereby providing a blended solution; and using the blended solution to prepare organic thin films in the manufacture of the organic thin film devices. Alternatively, the inorganic salt may be added directly to the first solution to provide an inorganic salt-doped solution that is then used to prepare the organic thin films in the manufacture of the organic thin film devices.

Abstract: A method and apparatus for manipulating ions using a two-dimensional substantially quadrupole field, and a method of manufacturing and operating an apparatus for manipulating ions using a two-dimensional substantially quadrupole field are described. The field has a quadrupole harmonic with amplitude A2 and a hexapole harmonic with amplitude A3. The amplitude A3 of the hexapole component of the field is selected to improve the performance of the field with respect to ion selection and ion fragmentation.

Abstract: A mass spectrometer having an elongated rod set, and a method of operating same. The rod set has an entrance end, an exit end and a longitudinal axis. Ions are admitted into the entrance end of the rod set. At least some of the ions are trapped in the rod set by producing a barrier field at an exit member adjacent to the exit end of the rod set and by producing an RF field between the rods of the rod set adjacent at least the exit end of the rod set. The RF and barrier fields interact in an extraction region adjacent to the exit end of the rod set to produce a fringing field. Ions in the extraction region are energized to mass selectively eject at least some ions of a selected mass to charge ratio axially from the rod set past the barrier field. The RF field is a two-dimensional substantially quadrupole field having a quadrupole harmonic with amplitude A2, an octopole harmonic with amplitude A4, and a hexadecapole harmonic with amplitude A8. A8 is less than A4, and A4 is greater than 0.1% of A2.

Abstract: A method and apparatus for manipulating ions using a two-dimensional substantially quadrupole field, and a method of manufacturing an apparatus for manipulating ions using a two-dimensional substantially quadrupole field are described. The field has a quadrupole harmonic with amplitude A2, an octopole harmonic with amplitude A4, and higher order harmonics with amplitudes A6 and A8. The amplitude A8 is less than A4. The A4 component of the field is selected to improve the performance of the field with respect to ion selection and ion fragmentation. The selected A4 component can be added by selecting a degree of asymmetry under a 90° rotation about a central axis of the quadrupole. The degree of asymmetry is selected to be sufficient to provide the selected A4 component.
