Abstract
A sensor assembly for electrochemical analysis of a substance comprises a housing and electrodes for sensing selective gases and ions within the housing. A sampler is associated with the housing for introducing the substance to be analyzed into the housing and for allowing the selective gas and ion content thereof to be sensed without physical contact with the gas and ion sensing electrodes. A method of detecting gases and ions in a substance comprises withdrawing a quantity of a substance from a source and directly contacting the substance with a gas and ion permeable medium as it is withdrawn from the source. Gases and ions are caused to permeate through the medium whereupon the gases and ions are detected by a sensing mechanism.
