Abstract
A gas cell for use in spectrometric analysis is disclosed, in which a series of pipes provide both the gas chamber and a light guide for infrared radiation which passes through the gas to accomplish the analysis. The light pipe is designed to provide a maximum radiation throughput of a collimated radiation beam. The same pipe provides laminar gas flow into and out of the gas cell. In other words, the gas when moving is not obstructed or restricted by changes in the cross-sectional area of its passageway.
