The demountable 10cm teflon gas cell is a development in reply to requests offered by the IR spectroscopy community. The cell is fabricated from solid teflon bar stock thereby eliminating the risk of gases permeating and absorbing into the surfaces of normally coated or surface treated metal bodied cells. Gas analysts have confirmed the teflon body prevents degradation and cross contamination from residual gas sampling.
The order details provide for a demountable 10cm teflon gas cell which offers a 25mm clear aperture and volume capacity of approximately 50ml. As pictured, assembly consists of threaded 1/4" teflon valves, black anodized threaded aluminum end caps, Viton® "o" rings and teflon gaskets. A slide mount accompanies the cell which features a locking mechanism to align and secure the cell. Standard 38mm x 6mm windows are required.
The optional choice of window materials include but are not limited to BaF2 Barium Fluoride, CaF2 Calcium Fluoride, KBr Potassium Bromide, KCl Potassium Chloride, KRS-5 Thallium Bromide Iodide, NaCl Sodium Chloride, Sapphire, ZnS Zinc Sulfide Cleartran and ZnSe Zinc Selenide.
