【 摘 要 】

Infrared spectroscopyis a versatile technique used for qualitative and quantitative determinationof all types of molecular species. As far as analysis of confined or flowinggases is concerned, different types of cell can be found in the market, butthey are often very expensive. This study describes the construction of a veryefficient gas cell with good reproducibility for qualitative infrared analysisof confined or flowing gases, using easily available and low-cost materials.
