摘要：

A long path absorption cell (Long White Cell) which has been designed and built for laboratory spectroscopic studies of gases found in terrestrial and planetary atmospheres is described. Factors influencing the design and construction are discussed, including aspects of the optical, mechanical, cryogenic, vacuum, gas handling and safety systems, and the pressure and temperature monitoring systems. The practical capabilities of the cell include absorber pathlengths up to 512 m, gas sample pressures up to 5 bar and temperatures between 190 and 300 K, and the suitability for use with corrosive and flammable gases. The performance of the cell is discussed in relation to spectroscopic measurements of mixtures of gaseous methane and hydrogen.
