Spectroscopic cell design |
摘要 |
The spectrographic sample cell for the analysis of trace impurities in sample gases. The cell is provided with a gas inlet, a gas outlet and a volume for confining the sample gases for analysis. Two mirrors are provided, a first mirror proximate the gas inlet the second mirror proximate the gas outlet, the first mirror having a hole at its radial center. A conically-shaped cell profile is further provided such that the formation of vortices of sample gas is prevented in the cell upstream of or in the region where the analysis of trace impurities is to take place.
