摘要： An ion trap includes a containment region for containing ions, and a plurality of electrodes positioned on a regular polyhedral structure encompassing the containment region. An electrode is positioned on each vertex of the encompassing structure and at least one of the polygonal surfaces includes additional electrodes configured to form a plurality of quadrupoles on the surface. Alternating RF voltage is applied to the plurality of electrodes, so that directly neighboring electrodes are of equal amplitude and opposite polarity at any point in time. This configuration on the polyhedral structure forms a potential barrier for repelling the ions from each of the regular polygonal surfaces and containing them in the trap. Mass selective filters can be formed from the quadrupoles for parallel mass analysis in different m/z windows. Application of a small DC potential to a plate electrode outside the quadrupoles preferentially depletes single charged ions for enhanced signal-to-noise analysis.

摘要： A discharge ionization detector (150) includes a sensor (50) that uses an alternating current discharge through a working gas as an ionization source. The sensor includes a discharge chamber (52), into which a sample gas is introduced. UV photons from the discharge chamber and metastable particles that enter the ionization chamber (53) from the discharge chamber (52) ionize molecules in the sample gas. The ions generated from the ionized sample gas are measured as a current indicating the quantity of ionizable molecules in the sample gas. For selective identification of molecules in the sample gas, one or more chemical filters can filter the sample gas to separate target gases from gases that interfere with detection of target gases. Additionally, a supply for the working gas can change the working gas to change the maximum energy available for ionization of the sample gas. Thus, current measurements with different working gases indicate quantities of classes of molecules having different ionization potentials.

摘要： Pulsed Field Magnetometry (PFM) method and apparatus to compensate for zero signal errors in a material characterisation process involving first constructing a synthesised zero signal expressed with a range of variable parameters. A measurement cycle is performed on a sample of material to be characterised the waveform data obtained in said measurement cycle is stored. The synthesised zero signal is then applied to the stored data while adjusting the values of the variable parameters, and the values are selected which best fit the synthesised zero signal to the stored data. The synthesised zero signal with the selected values is then removed from the stored data to obtain compensated material characterisation data.

摘要： A method and device for determining the existence of a leak in a package includes generating an AC high voltage with a DC high voltage offset in a circuit. A package is placed between an inspection electrode and a detection electrode, which are located within the circuit. The inspection electrode applies the AC high voltage with the DC high voltage offset to the package. Current flow through the package is then detected by the detection electrode. A detection board then processes the current flow and sends the processed signal to a programmable logic controller which determines if a leak is present in the package. If a leak is present, a signal is sent to a display to notify a user.
