GAS CELL FOR GAS ANALYZER

摘要

PROBLEM TO BE SOLVED: To provide a gas cell whose detecting sensitivity is not influenced by a flow rate and flow speed of gas by devising the constitution of the gas cell in a gas analyzer. SOLUTION: A gas cell of a gas analyzer is provided with a passage 10 which introduces a gas component and the infrared light to be measured and derived the gas component and the infrared light after the infrared light is absorbed by the gas component. This passage 10 is provided with an outer wall 10a having a conical wall part 13 and an inner wall 10b having a conical wall part 11 arranged in the axial direction so as to be opposed to this. The infrared light is introduced to the passage 10 from an infrared light introducing port 17 so as to advance by being multiply reflected in a spiral shape to the periphery of its axis between both wall parts 11 and 13. Gas is also introduced to the passage 10 from a gas introducing port 15 so as to advance in its axial direction along a part between both wall parts 11 and 13.
