  • Exhaust gas sampling mechanism and exhaust gas analysis apparatus
    Patent number: 10073014
    Abstract: To provide an exhaust gas sampling mechanism which can prevent condensed water droplets in exhaust gas from being sampled by a sampling probe and advantageously sample only the gas components of the exhaust gas to be measured, thereby maintaining a high response speed in analyzing the exhaust gas, the exhaust gas sampling mechanism includes the sampling probe disposed in a flow path through which the exhaust gas flows, for sampling the exhaust gas; and a gas-permeable cover which covers at least an upstream portion or a lateral surface portion of the sampling probe in the flow path, and has a water droplet removing structure.
