Abstract
857,631. Determining physical qualities of gases. MINE SAFETY APPLIANCES CO. Feb. 13, 1959 [Feb. 19, 1958], No. 5044/59. Class 37 A method of detecting the presence of an electro-negative gas contaminant in a mixture with a non electro-negative gas comprises ionising a moving stream of the gaseous mixture and subjecting it to electric field the electron current flow being compared with that produced under the same conditions by the non electro-negative gas alone. Fig. 1 shows an apparatus for testing the presence of traces of electro-negative oxygen gas in otherwise pure non electro-negative hydrogen. The pure hydrogen gas is passed through a detector chamber 1 having inner electrode 8 and outer electrode 2, the gas being ionised by the presence of an alpha radiation source 9, for example radium, inside the tube. The current flow between electrodes 2, 8 is detected in a Wheatstone bridge circuit which may for example be brought to a null condition by adjustment of potentiometer 16. A predetermined quantity of oxygen gas is then mixed with the hydrogen and passed through the detector chamber 1 and the change in current flow between electrodes 2 and 8 is detected. In order to compensate for changes in the ambient conditions, or the presence of contaminant gases other than oxygen, the resistor 15 may be replaced by a second chamber connected either in parallel or series for gas flow with the chamber 1, Figs. 2 and 3 (not shown). An oxygen filter is then placed before one of the chambers so that oxygen is extracted from the gas passing through one only of the chambers and the difference in electron current flow between the two chambers is measured. The gas contaminant to be detected may be oxygen, hydrogen chloride, sulphur dioxide, carbon monoxide or chlorine and the carrier gas may be hydrogen, helium, neon, argon, nitrogen, ethylene acetylene or paraffin hydrocarbon. The contaminant gas may consist of a mixture of any two or more electro-negative gases and likewise the carrier gas may be a mixture of two or more non electro-negative gases.
