AUTOMATIC GAS ANALYZER

摘要

PURPOSE:To sample and analyze a large number of specimen gases by one operator, by successively supplying the specimen gases collected by a large number of collection means to the transfer pipe communicating with an analyser through the corresponding automatic on-off valves. CONSTITUTION:Predetermined specimen gases are sampled in a large number of specimen sampling containers 11a-11i forming a collection means 11 from sampling points and said containers 11a-11i are respectively connected and mounted to the protruded parts of a piping system equipped with automatic on-off solenoid valves 12a-12i. These valves 12a-12i are successively opened through a control circuit 9 and the respective specimens of the containers 11a-11i are sent to the transfer pipe 1 connected to an analyser through a transfer means 14 and the valves 12a-12i after the completion of analysis are similarly closed automatically. By this constitution, the sampling and analysis of a large number of specimens for measuring the concns. of CO2 and O2 contained in specimens such as the exhaust gases of an engine can be performed by one operator and efficient analysis is performed under labor saving.
