8-80 Meter

8 - 80 Meter, 18 Liter Multi-Pass Gas Cell


High energy throughput 8 to 80 meter variable pathlength long path gas cells. It has a micrometer barrel adjustment that allows for easy, reproducible pathlength adjustment. The cell body and end plates are metal. This rugged construction is safer than Pyrex glass body construction.  The gas cells may be installed in a sample compartment or an external beam of a laboratory FTIR spectrometer. 

The description of this cell is outlined below.
