Abstract
In order to provide an absorption analyzer capable of directly measuring an analysis target gas flowing into or produced in a vessel such as a chamber and preventing a measurement error due to moisture condensation, the absorption analyzer is adapted to include: a light emission module that is attached covering a first opening of the vessel into which the analysis target gas flows or in which the analysis target gas is produced and emits light into the vessel; and a light detection module that detects the light emitted from the light emission module and passing through the vessel. In addition, the light emission module is adapted to include: a base flange that is attached around the first opening on an outer surface of the vessel; a window material whose outer surface is tilted at a predetermined angle; a seal member; and a pressing body.
