Plasma microreactor apparatus, sterilisation unit and analyser

摘要

Apparatus for the production of a product gas (eg hydrogen and ozone) comprises: a supply of reactant gas (eg oxygen and steam); a pair of electrodes with a space between them of less than 1 mm; a conduit to lead the reactant gas from the source through the space between the electrodes; a power source to apply a voltage across the electrodes to dissociate the reactant gas and ultimately permit formation of product gas; and a conduit to supply the product gas to an outlet. A sterilisation unit for water treatment employs such apparatus and includes a fluidic oscillator to oscillate the flow of oxygen and/or ozone, and wherein said outlet comprises a plurality of orifices to be submerged in said water and for the purpose of forming micro bubbles of ozone. An analyser for detecting large organic molecules in eg air can employ the ozone generator to breakdown the large molecule into simpler and easier-to-detect-and-identify molecules.
