<p>PURPOSE: To provide an infrared gas analyzer which allows high sensitivity measurement and can be used as an in-line monitor to be inserted in a gas passageway, by making the size of a light source and cell as small as possible so that the power consumption and heat transfer to surrounding areas are suppressed as much as possible. CONSTITUTION: An infrared ray transmission-aperture 21 of a light source 2 and an infrared ray transmission aperture 31 of a detector 3 are assigned proximately at the opposite position, and, a gap between bath infrared ray transmission apertures 21 and 31 is assumed as a cell 1 inserted into gas passageways 70 and 71, and, at least two pyroelectric elements 5 and 6 are provided in the detector 3.</p> |
