Pure nitrogen generator Khielectronics GChA-21D

Pure nitrogen generator GCHA-21D The pure nitrogen generator GChA-21D is intended for laboratory production of nitrogen of the highest purity, used to power analytical instruments (chromatographs, including those equipped with an electron capture detector, express analyzers of hydrogen content in metals, organic carbon concentration meters, sample evaporators, etc.), boxes with an inert atmosphere. The device is an analogue of GChA-21, but is equipped with a built-in system for catalytic purification of the resulting nitrogen from hydrocarbons.
