Japanese Patent JPS5162786
Kind Code:
A
Abstract:
A combustion system includes a combustion furnace for combusting a solid or liquid specimen and converting it to a gaseous mixture. The furnace is positioned in a circulatory loop in which oxygen is introduced to complete the combustion of the specimen into a gaseous mixture which is circulated through the furnace to fully oxidize the specimen and maintain the specimen gas concentration level constant during a measurement interval. To facilitate circulation of the gases in the loop, a circulation pump is employed in the flow path. In one embodiment, a detector is included in the loop while in alternative embodiments, an aliquot of the specimen gases is removed for analysis by a detector outside of the loop.
