Demountable gas cells for IR spectroscopic analysis of gaseous samples


Our demountable gas cells are available in Pyrex®, stainless steel and PTFE. For samples with higher concentrations, we recommend the cell with 5 cm path length. Viton O-rings ensure a gas tight seal (PTFE O-rings available as spare parts) and the cells are filled using a gastight syringe that you will need to purchase separately. To use the cells you will need two undrilled 25 mm Ø x 4 mm IR windows that are not included. We offer these in the following materials: NaCl, KCl, KBr, CaF2, BaF2, Csl, KRS-5, AgBr, ZnS, ZnSe, SiO2 and AgCl.
