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.

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.

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.

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.

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.
