A gas cell for infrared analysis of gaseous samples

摘要

A gas coil to the analysis of gaseous samples in an infrared spectrometer has at least one focusing mirror 22, 23 by means of which a beam 30, 33 may be focused and reflected to a second focus 26. There is an entry window 25 for the incoming rays and an exit window 26 for the rays 37 leaving the cell, each being positioned in a respective focus. The gas cell may be used at temperatures up to 350 DEG C in conjunction with aggressive materials. The main application for the gas cell is fluorine combustion analysis.
