Abstract
A multi-component gas analyzer includes a light source system, a cassette-type light path system, an optical folding system, and an infrared detecting system. The light source system has an infrared light source and a reflector for providing a parallel infrared light beam. The cassette-type light path system has a cassette, an optical absorption chamber, and a set of concave mirrors. A vent hole set is provided having a plurality of vent holes enclosed by an O-ring for sealing the gas between the stacked-up cassettes. The optical absorption chamber includes a highly reflective coating film coated on the inner wall surface thereof that is employed for introducing the gases to be analyzed and provides a space for contact between the gases and the infrared light.
