Low Volume, Long Path Gas Cell
This low volume (0.2 liter) gas cell has a path length of 3 meters. It has been designed to be installed in any FTIR spectrometer’s sample compartment. The drawing below shows its major features of a stainless steel version. The gas cell can be made of Ni coated aluminum, 316L stainless steel, or nickel. The standard windows are KBr, but other materials maybe used. The standard o-rings are Viton, but again other o-ring materials such as Teflon, Kalrez, etc.
This configuration is excellent for a 3 meter gas cell with low volume for some GC and LC applications where one needs a longer pathlength and high temperatures up to 200 degrees Celsius for Ni coated Al and higher temperatures for short periods of time using stainless steel construction.
