Abstract
In the gas detector the gas stream to be investigated is conveyed past one of two electrodes of a measuring cell. The two electrodes are in contact with an electrolyte, wherein the electrolyte is an anhydrous organic gel. The gas component to be measured changes the electrochemical equilibrium at one of the two electrodes and produces thereby in the outer closing circuit a measurable electrical current which is a measure of the concentration of the gas component, to be detected.
Claims54
In an electrochemical gas detector for measuring traces of a component of a gas mixture comprising a cell comprising two electrodes and an organic electrolyte between and in contact with said electrodes, an outer closing circuit connected to said electrodes for flow of an electric current through the electrolyte and the outer closing circuit, said outer closing circuit including measuring means responsive to flow of current in the outer closing circuit, means for introducing a gas mixture into said cell, said cell being adapted for contacting the gas mixture with the electrolyte for changing the electrochemical equilibrium at one of the electrodes for generation of an electrical current in the outer closing circuit, the improvement which comprises said electrolyte consisting essentially of an anhydrous organic gel.
