ABSTRACT:
An apparatus, viz., a moisture analyzer, for the detection, and measurement of moisture in trace amounts in fluid streams, especially gas streams. The moisture analyzer is characterized as (A) a cell assembly constituted of a compartmented structure (i) a first compartment separated from a second compartment by a partitioning semi-permeable membrane through which moisture can be passed, said first compartment including a fluid, or gas inlet into which a moisture-containing fluid, especially a gas, can be admitted, and a fluid, or gas outlet from which fluid, or gas, can be expelled, (ii) the second compartment containing an electrical circuit which includes at least one pair of electrically isolated electrodes located in close proximity one to another, upon which electrodes can be disposed a hydroscopic substance, or electrolyte, e.g., P.sub.2 O.sub.5, which is electrically conductive when wet and in contact with both electrodes, (B) a direct current power source of voltage sufficient to electrolyze said hydroscopic substance, or electrolyte, when it is wetted by moisture passed through said semi-permeable membrane from the first compartment to said second compartment, (C) current measuring means connected in circuit with said power source for measuring the water content of said hydroscopic substance, or electrolyte as a function of the current delivered by said power source in electrolyzing said hydroscopic substance.
