Publication number: 20100290171Abstract: A method produces a bipolar ionic atmosphere using a dielectric barrier discharge, and to a device suitable for carrying out the method. The solution for achieving this aim is to trigger an electrical surface discharge at more or less regular intervals on the wall of a channel through which a gaseous medium flows. The flow channel is formed by a dielectric and a wall electrode such that the channel wall consists in the direction of flow alternately of a conductive electrode material and a dielectric. In principle it will suffice if the channel is formed of only one dielectric and one conductive section which adjoin each other. The electrical surface discharge is triggered by a second electrode which is separated by the dielectric from the wall electrode and the flow channel, and to which a temporally varying high voltage is applied by an impulse generator.Type: ApplicationFiled: May 17, 2010Publication date: November 18, 2010Applicant: GIP MESSINSTRUMENTE GMBHInventors: Markus Wild, Gerhard Kasper

Patent number: 4794086Abstract: Method and apparatus for the measurement of sub-ppm concentrations of impurities in liquids. The liquid to be measured for impurities is dispersed into uniform droplets of a precisely known diameter D in a gas stream, such as air, using for example, a vibratory orifice generator. The dispersed droplets evaporate in the gas stream to leave a residue particle having a diameter d, which can be measured for example by means of a laser light scattering spectrometer. The concentration by volume, C.sub.v, of the impurities can then be calculated according to the equation; C.sub.v =(d/D).sup.3.Type: GrantFiled: November 25, 1985Date of Patent: December 27, 1988Assignee: Liquid Air CorporationInventors: Gerhard Kasper, Horng Y.
