  • Publication number: 20200363373
    Abstract: A method of manufacture for a ion mobility filter is disclosed. The method of manufacturing an ion filter for a spectrometry system includes providing a sheet of conductive material and defining a plurality of ion filters on the sheet. The definition of the plurality of ion filters is achieved by forming an electrode layer for each ion filter on the sheet, where each electrode layer comprises at least one ion channel and an isolation channel surrounding the at least one ion channel. A support layer on each electrode layer is also formed. Each support layer comprises an aperture at least partially aligned with the at least one ion channel. The ion filter is then separated. The risk of contaminants entering the at least one ion channel when separating the ion filters is reduced by surrounding the at least one ion channel with the isolation channel.

  • Publication number: 20200278319
    Abstract: An ion filter for filtering ions in a gas sample. The ion filter has a first ion channel for filtering ions from a target chemical in the gas sample. The ion filter has a second ion channel for filtering ions from the target chemical in the gas sample. The second ion channel is separated from the first ion channel. A temperature control region is in thermal contact with the first and second ion channels for controlling a difference in temperature between the first and second ion channels. A method of filtering ions from a target chemical in a gas sample is also provided.

  • Publication number: 20200232945
    Abstract: An ion mobility filter is disclosed. The present invention relates to but not exclusively a field asymmetric ion spectrometry filter. For example, we describe an ion filter for filtering ions in a gas sample. The ion filter is comprised of a plurality of electrodes, a first ion channel, and a second ion channel. The first ion channel filters ions from a target chemical in the gas sample, defines a gap between a first pair of electrodes in the plurality of electrodes, and has a first ion channel gap width. The second ion channel filters ions from the target chemical in the gas sample, defines a gap between a second pair of electrodes in the plurality of electrodes, and has a second ion channel gap width. The first ion channel gap width is greater than the second ion channel gap width.

  • Publication number: 20200008710
    Abstract: Disclosed is apparatus for collecting a breath sample from a human subject, the apparatus comprising at least a mask portion which, in use, is positioned over the subject's mouth and nostrils so as to collect breath exhaled from the subject, the apparatus further comprising movement detection means for detecting movement of the mask portion, and an alarm signal generator, which alarm signal generator generates an alarm signal if the subject's head is outside a predetermined range of acceptable orientations during collection of a breath sample, but only after the subject's head has been outside the predetermined range of acceptable orientations for a defined or measurable period of time.

  • Patent number: 10026600
    Abstract: A corona discharge ionizer device which emits ions generated by corona discharge to a gas flow to be ionized includes a discharge electrode having a pin configured tip portion. A second grid electrode positioned at a spaced distance from the discharge electrode is provided. The grid electrode is preferably formed from a sheet configured material which has at least one hole formed therein adapted and configured to permit the gas flow to pass therethrough. A power supply is coupled to the discharge electrode and grid electrode configured cause ion emission from the discharge electrode. The power supply is preferably an alternating current power supply configured to produce an alternating electric field region in close proximity to the tip portion of the discharge electrode sufficient to cause avalanche breakdown in the gas flowing in close proximity to the tip portion of the discharge electrode.

  • Patent number: 9976985
    Abstract: An apparatus, system and method for detecting, identifying, classifying and/or quantifying chemical species in a gas flow using a micro-fabricated ion filter coupled to a system adapted to apply drive signals to the ion filter. Coupled to the ion filter is a system adapted to measure the output of the ion filter, which in turn is coupled to a system adapted to extract numerical parameters from the measured output of the ion filter to facilitate chemical detection, identification, classification and/or quantification of the gas flow.
