Method for measuring the concentration of a combustible component |
摘要 |
A method of measuring a combustible component in a liquid or gas employs a gas having a high oxygen content, instead of air or an inert gas, as the carrier gas to thereby improve drastically the scope and accuracy of measurement by a semicondutor gas sensor. The carrier gas having a high oxygen content is supplied into a combustible component sampler formed from a gas-permeable membrane and disposed in the liquid or gas to be tested so that the combustible component may be diffused into the carrier gas through the gas-permeable membrane. The carrier gas entraining the combustible component therein is introduced into a detector having a semiconductor gas sensor, in which the combustible component is detected, and its concentration is determined continuously or intermittently.
