20110240850 | Microengineered Multipole Ion Guide - A microengineered multipole ion guide for use in miniature mass spectrometer systems is described. Exemplary methods of mounting rods in hexapole, octupole, and other multipole geometries are described. The rods forming the ion guide are supported in etched silicon structures defined in at least first and second substrates. | 10-06-2011 |
20110240849 | Microengineered multipole rod assembly - A method of mounting rods in quadrupole, hexapole, octupole, and other multipole geometries is described. First and second dies are used to hold the rods in the required configuration with the plurality of rods extending through each of the two dies. A coupling arrangement is used to separate the first and second dies, and also prevents motion in the plane of the dies. The rods are seated and retained against individual supports and arranged circumferentially about an intended ion beam axis. The supports are desirably fabricated from silicon bonded to a glass substrate, a support for a first rod being electrically isolated from a support for a second adjacent rod. | 10-06-2011 |
20110192215 | Analytical System for In-Line Analysis of Post-Combustion Capture Solvents - A device and method is described for direct analysis of solvents used to chemically bind with CO | 08-11-2011 |
20110127423 | Mass Spectrometer System - This invention describes an analytical system where a kinetic impact ionisation source is combined with an RF—only ion guide to form a mass spectrometer system for analysis of the elemental and chemical composition of exoatmospheric particles. The kinetic impact ionisation source may be used to transform a flux of particle debris into a beam of ions for analysis by a mass analyzer. | 06-02-2011 |
20110127421 | Sample Collection and Detection System - A sample collection and detection system is described. The detection system provides a sample chamber fluidly coupled to a secondary ionisation source to allow the introduction of vapour generated from the sample into an ion path generated from the secondary ionisation source. The secondary ionisation source is a secondary electrospray ionisation (SESI) source, and is usefully employed in dust analysis. | 06-02-2011 |
20110101220 | High Performance Micro-Fabricated Quadrupole Lens - This invention provides 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. 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. | 05-05-2011 |
20110084202 | Portable Analytical System for On-Site Analysis of Fluids - A portable analytical system for the rapid on-site analysis of fluids, and a method for using this system at the well-site for the analysis of samples extracted from drilling fluids is described. The portable analytical solution may be deployed at the well-site and used to perform detailed real-time analysis of formation fluids and extracts of rock cuttings. The method described could be used during hydrocarbon exploration and production to determine whether the drill stem has passed through a hydrocarbon-bearing region, or rocks that are capable of functioning as an oil reservoir or that may have been a source rock, or that may have come into contact with oil, or that may contain oil at present. | 04-14-2011 |
20100276591 | Electrode Structures - This invention describes an electrode structure formed from a plurality of individual electrodes, the individual electrodes being provided on separate submounts, the submounts being coupled to one another using kinematic ball mounts. Such a structure may be configured as a RF ion guide, mass filter or ion trap. | 11-04-2010 |
20100276590 | Microengineered Vacuum Interface for an Ionization System - A planar component for interfacing an atmospheric pressure ionizer to a vacuum system is described. The component combines electrostatic optics and skimmers with an internal chamber that can be filled with a gas at a prescribed pressure and is fabricated by lithography, etching and bonding of silicon. | 11-04-2010 |
