摘要： An electrostatic ion trap or an array of electrostatic ion traps are provided having a longitudinal length of no more than 10 mm and/or at least one electrode with a capacitance to ground of no more than 1 pF. First and second sets of planar electrodes may be distributed along the longitudinal axis, at least some of the which are configured to receive an electrostatic potential for confinement of ions received in the space between the first and second sets of planar electrodes. An array may comprise an inlet for receiving an ion beam, configured such that a portion of the ion beam can be trapped in each of the ion traps. Signals indicative of ion mass and charge data may be obtained from multiple electrostatic ion traps in the array. This mass and charge data may be combined for identification of components of a mixture of different analyte ions.

摘要： A mass analyzer includes a main substrate, an upper substrate adhered to the main substrate, and a lower substrate. A mass analysis room (cavity) is formed in the main substrate and penetrates from an upper surface of the first main substrate to a lower surface of the first main substrate. A vertical direction (Z direction) to the main substrate by the upper substrate, both sides of the lower substrate, a travelling direction (X direction) of charged particles and a right angle to the Z direction by the main substrate, and both sides of a right-angled direction (Y to Z direction) and the X direction by a side surface of the main substrate are surrounded. A central hole is open in the side plate of the main substrate that the charged particles enter. The charged particles enter the mass analysis room through the central hole formed in the first main substrate.

摘要： An ion guide for mass spectrometry comprising an electrode arrangement of at least two electrodes, at least one of which is an RF electrode, arranged adjacent to each other but spaced apart on a planar surface of a dielectric material and arranged at a distance from an ion flow path, wherein a portion of the dielectric surface is exposed between an adjacent pair of the spaced apart electrodes and wherein at least one electrode of said adjacent pair of electrodes is arranged to overhang the exposed portion of surface between them such that there is no direct line of sight from the ion flow path to the exposed portion of dielectric surface. The device enables RF guiding of ions accompanied by much reduced charging-up of dielectric surfaces and reduced amount of collisions of neutral species with electrodes.

摘要： An ion detection assembly is described that includes a drift chamber, an inlet assembly, and a collector assembly. The drift chamber is formed of substantially non-conductive material and/or semi-conductive material. A patterned resistive trace is deposited on one or more of an interior surface or an exterior surface of the drift chamber. The patterned resistive trace is configured to connect to a source of electrical energy. The inlet assembly and the collector assembly are in fluid communication with the drift chamber. The inlet assembly includes an inlet for receiving a sample, a reaction region for ionizing the sample, and a gate for controlling entrance of the ionized sample to the drift chamber. The collector assembly includes a collector plate for collecting the ionized sample after the ionized sample passes through the drift chamber.
