    Abstract: A particle inlet system comprises a first chamber having a limiting orifice for an incoming gas stream and a micrometer controlled expansion slit. Lateral components of the momentum of the particles are substantially cancelled due to symmetry of the configuration once the laminar flow converges at the expansion slit. The particles and flow into a second chamber, which is maintained at a lower pressure than the first chamber, and then moves into a third chamber including multipole guides for electromagnetically confining the particle. The vertical momentum of the particles descending through the center of the third chamber is minimized as an upward stream of gases reduces the downward momentum of the particles. The translational kinetic energy of the particles is near-zero irrespective of the mass of the particles at an exit opening of the third chamber, which may be advantageously employed to provide enhanced mass resolution in mass spectrometry.

In a specific example, the particles are sorted using a differential mobility analyzer, which sorts particles, at least in part, based on their electrical mobility. Given a population of particles with similar electrical mobilities, the disclosed process can be used to sort particles based on the net charge carried by the particle, and thus, given the relationship between charge and morphology, separate the particles based on their morphology.

  • Publication number: 20100294129
    Abstract: Liquid and/or particle-shaped impurities are precipitated from a stream of gas, for example, from a stream of gas that originates from a crankcase of an internal combustion engine and is directed to the engine's intake side. The stream of gas is passed through a gas discharge section between two electrodes. The stream of gas is passed between an emission electrode which is formed by electrode tips and an opposing electrode at a distance therefrom. A direct voltage which exceeds the breakdown voltage is applied to the electrodes using a direct current high voltage source, and the current which occurs over the gas discharge section between the electrodes is limited. A stable low energy direct current plasma is formed in the space between the two electrodes. The impurities are electrically charged and attracted to the opposing electrode by means of electrical field forces.

  • Patent number: 7615106
    Abstract: A control device repeats first air volume control and second air volume control for a predetermined number of times irrespective of a control state at that time while forcedly driving an ion generator, when a bacteria elimination shower switch is turned on. In the first air volume control, a sirocco fan generates an air flow having a predetermined air volume. In the second air volume control, the sirocco fan generates an air flow having an air volume smaller than the predetermined air volume. Therefore, a bacteria elimination effect is enhanced in an air conditioning apparatus.
