Title: Analysis method of hydrogen gas
Inventor: AKIYAMA SIGEYUKI
IPC: G01N3/00
Filed: 1977-12-26
Granted: 1981-09-22
Abstract: Characteristics of this method is that low conc. of H2 can be measured as high conc.with a comparatively high-speed response or precision.  Thus, H2 in the sample was oxidized to give moisture, H2O and the quantity of H2O in which H2 was measured was determined by a highly effective moisture meter.  When the sampling gas contained moisture, the measurement occured after it was removed or removed at saturation condition to a degree of constant quantity by pseudo condensation.  If oxygen in the sampling gas is defficient, the oxygen in air can be mixed at a constant rate.
