GAS ANALYZER COMPRISING GAS PERVIOUS/LIQUID IMPERVIOUS MEMBRANE

摘要

A gas analyzer cell includes an insulator body having a central passage divided into a first cell chamber and a second expansion chamber by a flexible expansion membrane. The cell chamber contains an anodic mass of a nonpolarizable metal and is enclosed by a uniformly curved cathodic member of polarizable metal which is covered by a membrane impervious to liquid but pervious to gas. An electrolyte fills the cell chamber. The cathode and the gas permeable membrane are covered by a fibrous layer which is pervious to gas and is in turn covered by a metallic mesh held in place by a ring disc held securely to the insulator body. The metallic mesh and the fibrous layer hold the cathode membrane uniformly and tightly against the cathode of the cell so that the membrane does not lift or change its position under conditions of increased internal pressure and, consequently, incorrect results are eliminated.
