Gas Cell Options

The pathlength ranges from about 1 meter to 200 meters. Materials range from glass, nickel coated aluminum, stainless steel, nickel coated stainless, to solid nickel depending on the applications. The windows depend on the applications and are typically KBr, KCl, ZnSe, CaF2, BaF2, quartz, or sapphire. The O-rings range from Viton, Kalrez, Chem-Rez, Teflon, and metal seals made of copper or nickel.  Other materials are available depending on the application.  

Please note we work on custom designs to meet special application requirements.

The following table highlights just some of the pathlengths and volumes available.  There are actually more options than listed.  We can pretty much make a fixed pathlength cell for any of the variable pathlength ranges for the corresponding volume listed.

200 Meter Cell

Typical layout for 200 meter gas cell.

The gas cell body can be metal or glass. The pathlength can be doubled for the same base path and diameter using corner cube optics.
