| abstract |
A METHOD AND APPARATUS FOR DETERMINING OXIDIZABLE ORGANIC COMPOUNDS IN HUMAN AND ANIMAL BODY GASES AND FLUIDS. GASES TO BE TESTED ARE INTRODUCED, TOGETHER WITH EXCESS OXYGEN, INTO A VESSEL CONTAINING A HEATED METAL CATALYST. THE RESULTING CHANGES IN ELECTRO-PHYSICAL VALUES OF THE CATALYST, E.G., TEMPERATURE AND RESISTANCE, WHICH ARE DEPENDENT ON THE CONCENTRATION OF OXIDIZABLE COMPOUNDS CONTAINED IN THE GAS, ARE MEASURED TO PROVIDE AN INDICATION OF THE CONCENTRATION OF THE OXIDIZABLE COMPOUNDS. |
