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.

摘要翻译：要解决的问题为了解决与其他系统如鼓泡系统相比，膜渗透系统的油气分析仪需要大量时间用于气体收集的问题。解决方案：由气体渗透膜和带槽凸缘形成的气体储存室具有规定体积的细长形状。当收集气体时，气体通过气体渗透膜扩散到储气室侧。在测量气体时，从气体储存室的端部供给载气，用载气代替气体储存室，从另一端输出规定量的取样气体供给气体测定装置。在气体储存室中测量样品气体，从而省去测量管。通过采用细长的槽形状，可以减少施加到气体渗透膜上的剪切应力，从而可以减薄气体渗透膜的厚度。因此，可以缩短气体收集所需的时间。版权所有（C）2008，JPO＆INPIT
