An ultraviolet light source is provided on one end of a cell into which a sample gas is introduced. A beam splitter for dividing beams which have been transmitted through the cell into two optical paths is provided on the other end of the cell. A first detector is provided in one optical path, and a second detector is provided in the other optical path. A gas filter filled with a component to be measured is positioned between the detectors and beam splitter so that a concentration of the component to be measured may be obtained on the basis of a differen...
An ultraviolet gas analyzer comprising: a cell into which a sample gas is introducible; an ultraviolet light source provided at one end of said cell for providing beams of ultraviolet light; a beam splitter provided at the other end of said cell for dividing beams which have transmitted through said cell into a first optical path representing reflected ultraviolet light and a second optical path representing transmitted ultraviolet light; a first detector disposed in said first optical path, said first detector generating an output responsive to the refl...
