Abstract
In order to completely decompose remaining urea contained in exhaust gas emitted from an internal combustion engine to make it possible to accurately measure an amount of the remaining urea, as well as preventing measurement accuracy and reliability from being damaged by some cause such as the attachment of powdery urea on a sensor, a gas analysis apparatus is provided with a filter part that is provided between a sampling port and a produced substance measuring mechanism in a mixed gas sampling pipe to collect urea in a solid state or in a state of being dissolved in water in mixed gas.
