Rugged 5 cm short path gas cell

for the

Bruker Alpha FTIR Spectrometer

(and other FTIR spectrometers)

This small volume (~15 cc) gas cell is mounted on a slide mount as shown below. It has a path length for 5 cm and an internal diameter of about 20 mm. This gas cell is made of 316L stainless steel and uses 4 mm x 25 mm diameter windows. The gas stream input/output connections is made with 1/4” VCR fittings allowing for easy and reliable make and break connections. The standard O-rings and windows provided are Viton and KBr, respectively. Other O-rings such as Teflon, Kal-Rez, Butal, etc. and windows such as CaF₂, BaF₂, ZnSe, etc. are available as options.  The choice of O-rings and windows is dependent on chemical properties of the gases that will be in contact with the gas cell.
