  • Isotopic gas analyzer and method of judging absorption capacity of carbon dioxide absorbent
    Patent number: 6940083
    Abstract: In an isotopic gas analyzer, a gas injector (21) is provided for pressurizing a gas specimen in cells (11a,11b). The pressurization of the gas specimen virtually produces the same effect as increasing the concentration of carbon dioxide in the gas specimen, thereby improving an S/N ratio for the analysis and hence data reproducibility.
    Type: Grant
    Filed: September 19, 2001
    Date of Patent: September 6, 2005
    Assignee: Otsuka Pharmaceutical Co., Ltd.
    Inventors: Masaaki Mori, Yasuhiro Kubo, Masahiko Miyoshi, Tamotsu Hamao, Hiroaki Mizui
