  • Patent number: 10345093
    Abstract: An arrangement for determining four-dimensional properties of an interface of an object, including a light source includes: a unit for forming photonic jets, a unit for performing large field of view interferometric imaging of the interface and their combination, a unit for passing the light being close to the interface and direct the light to the interface, and an image unit. The arrangement includes a unit for performing phase shifting interferometric imaging of the interface, imaging a unit for receiving light from the interface modulated by e.g. microspheres for forming super-resolution image information by combining light interferometry with the photonic jets, and a processor unit for determining four-dimensional properties of the interface on the basis of the image information formed by the phase shifting interferometric imaging by utilizing effect of the photonic jets. The arrangement also can also include a unit to carry out the measurement using polarized light.

  • Patent number: 9916972
    Abstract: A device for ionizing sample particles of a sample gas flow comprises a first flow tube for providing the sample gas flow, and an introducing means for providing H2SO4 molecules to an interaction region. In addition the device comprises a generator for producing reagent primary ions from particles of candidate reagent gas flow essentially in a primary ion production region. The device is configured to introduce said reagent primary ions with H2SO4 molecules in said interaction region in order to arrange interaction between the reagent primary ions and the H2SO4 molecules, thereby producing HSO4? ions and again to produce HSO4? ion clusters comprising HSO4? ions and at least two H2SO4 molecules via interactions of HSO4? with other H2SO4 molecules in said interaction region.

  • Publication number: 20140302616
    Abstract: Properties, such as concentrations, of gas phase bases or acids of a gas sample are determined by providing a sample gas flow, which includes the bases or acids to be determined as sample constituents, as well as also interfering constituents, which are other constituents than the sample constituents. Reagent ions are provided and introduced into the sample gas flow to arrange proton transfer reaction and thereby forming sample ions. Also a dopant is introduced into the sample gas flow to arrange proton transfer reaction between the dopant and the interfering ions thereby forming dopant ions and electrically neutral interfering constituents. For determination the gas flow with the sample ions to be determined is introduced together with the dopant ions to a mass spectrometer in order to determine the properties of the gas phase bases or acids.
