<p>Method of indicating the presence of a detectable gas in gas-generating or gas-consuming reactions, by the use of a hydrogen and ammonia sensitive, palladium coated semiconductor device (Pd-MOS-FET). The measurements are carried out in the gas phase in a gas detector which is disposed in association with the reaction vessel in which the reaction which is to be studied takes place. A particular study has been made of enzymatic reactions in which hydrogen and/or ammonia are generated by the action of the enzyme urease on urea and creatininase on creatinine. </p> |
