Abstract

1429848 Detecting gases electrically HOCHVAKUUM DRESDEN VEB 8 June 1973 [9 June 1972] 27329/73 Heading G1N The partial pressure of inorganic and organic gases is determined by measuring the electrical conductivity of a single organic solid molecular compound exposed to the gases. The gases such as oxygen, hydrogen, carbon monoxide, carbon dioxide interact with the solid compound in a chemisorption process which changes the electrical surface properties and its conductivity. In one embodiment a cell is formed by depositing a pair of spaced metal electrodes on a quartz substrate and depositing a thin paste layer of all-trans-betacarotene over the electrodes and substrate. Alternatively a mono-crystal of all-trans-beta-carotene is applied to the substrate and then the spaced electrodes applied thereto. The cells so formed by be fastened to a P.T.F.E ring in the centre of which is a thermostatically controlled metal box in contact with the cell for maintaining its temperature constant. The P.T.F.E ring is supported by struts on a flange. The electrode leads are connected in series with a source of D.C., and measuring amplifier which latter is connected to an indicator.
