OPTICAL GAS ANALYSIS DEVICE, GAS ANALYSIS METHOD AND ANALYSIS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical gas analysis device that analyzes gas with higher accuracy.

SOLUTION: To solve the problem by making the optical gas analysis device include: a measuring cell where gas to be measured flows; an emission part that emits a laser beam; an optical system that guides the laser beam projected from the emission part to the measuring cell; a receiving part that receives the laser beam made incident from the optical system and having passed the measuring cell; an analysis part that analyzes the gas that flows in the measuring cell based on information acquired by the receiving part; and a temperature adjustment means that adjusts a temperature of the optical system.
