Abstract

PURPOSE:To enalbe the cell to be used as an ordinary measuring cell and enable the same to be used as a standard cell for calibration by enabling the specified amount of the gas to be detected to be dealed in the specified volume of the cell and further stirring this gas in the cell. CONSTITUTION:The inside volume of an injector 27 is beforehand determined and as a piston 40 iw pushed out, a differential pressure valve 26 is held open and the specimen gas is injected into the cell through injection port 25. The cylindrical magnet 32 which is secured to the magnet holding frame 31 mounted to the shaft 30 directly coupled to a motor 29 revolves on the outside of the cell. A thin slide ring 35 is provided on the inside surface of a seal frame 33, bounding at the outside surface of the shaft 36 journaling the columnar magnet 37. Since the magnets 32, 37 have magnetic poles in the circumferential direction, the magnet 37 revolves as the magnet 32 revolves. In this way, the gas having been injected may be evenly stirred without affecting the measured values.
