Title: Method for measuring concentration of ozone gas
Inventor: KOIKE KUNIHIKO
IPC: G01N7/00
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To detect a concentration of ozone gas from low to high level even with a small constant amount of a sample gas, by letting the sample gas decompose itself and measuring a degree of a pressure change. SOLUTION: A sampling conduit is branched from an ozone gas fed path. A sample ozone gas is filled in a sealed container of a predetermined volume set in the conduit. An internal gas is heated to not lower than 60 deg.C in an air- tight state, thereby letting the whole of an ozone gas component decompose itself. Thereafter, the sealed container is forcibly cooled until the temperature of the internal gas becomes a temperature at the introduction time. An internal pressure is measured by a pressure detection means, and a rate of a pressure rise is detected. A concentration of ozone in the sample gas is thus measured. If the sample gas is of 100% ozone, because of a change subsequent to the self decomposition of the ozone gas, the pressure is increased to 1.5 times when the volume is constant. Since a circulation gas at an ozone feed system is ozone and oxygen, the pressure is increased by an amount corresponding to the ozone gas decomposing itself to oxygen.
