METHOD OF COLLECTING ANALYTICAL EXHAUST GAS CONTAINING HIGH ADSORPTIVITY GAS COMPONENT

摘要

PROBLEM TO BE SOLVED: To accurately analyze the concentration of an ammonia gas component in exhaust gas. SOLUTION: In the method, the ammonia gas adhering to the inner wall of a duct 2 for collecting the exhaust gas as an object, is cleaned from the duct wall, by using a liquid absorbing the ammonia gas as the cleaning liquid. The gas component is fully recovered by the method. An analyzed result is obtained with high precision by analyzing the cleaning liquid. COPYRIGHT: (C)2004,JPO
