摘要： PROBLEM TO BE SOLVED: To solve the problem wherein an in-oil gas analyzer of a membrane permeation system requires much time for gas collection in comparison with another system such as a bubbling system.
SOLUTION: A gas storage chamber formed from a gas permeating membrane and a grooved flange has an elongate shape with a prescribed volume. When collecting gas, gas is diffused to the gas storage chamber side through the gas permeating membrane. When measuring the gas, carrier gas is supplied from the end of the gas storage chamber to replace the gas storage chamber with the carrier gas, and a prescribed amount of sample gas is sent out from the other end and supplied to a gas measuring device. The sample gas is measured in the gas storage chamber, to thereby dispense with a measuring tube. A shearing stress applied to the gas permeating membrane can be reduced by adopting an elongate groove shape, and thereby the thickness of the gas permeating membrane can be thinned. Hereby, a time required for gas collection can be shortened.
