Abstract

PURPOSE: To remove the effect of interferece components by disposing a second detecting vessel after a first detecting vessel of a gas sealed type and movable composing a reflecting plate so that the infrared rays having transmitted through the second detecting tank may be partially reflected again to the second detecting vessel side.
