Abstract: A system for identifying gases, the system having a plasma generator for generating a plasma using the gas to be identified and an array of detectors for detecting light emitted from the plasma. By analysing the output of the detectors, the gas can be identified. The system includes a plasma display (11) having two glass plates (36 and 38) patterned with strips that form the plasma electrodes. The intersection between the strips defines pixels which are individually addressable.

Abstract: A method for the modification of a surface of a silver electrode wherein the surface is treated with a chlorine plasma is described. Control of the power, flux density and timing provide the manner to modify the silver surface, and so implant the chlorine atoms and ions into the silver. The present invention provides a method to produce thin-film silver electrodes with a very controlled surface. Such electrodes can provide quantitative quality of measurement. The present invention extends to a method for the modification of a surface of any metal wherein the surface is treated with a plasma.

Abstract: An apparatus for coating a substrate with a diamond like coating or other vacuum depositable material comprises a chamber 11 having, or acting as, an anode, means for supporting a substrate 15 in the chamber, means for establishing a low pressure atmosphere containing a hydrocarbon-based gas in the chamber, and a radio frequency source 12 for establishing a gas plasma in the chamber, the substrate 15 acting as a cathode.
