Product Description

The demountable 10cm PTFE gas cell is a development in reply to requests offered by the IR spectroscopy community. The cell is fabricated from solid PTFE 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 PTFE body prevents degradation and cross contamination from residual gas sampling.

The order details provide for a demountable 10cm PTFE gas cell which offers a 25mm clear aperture and volume capacity of approximately 50ml. As pictured, the assembly consists of threaded 1/4" PTFE valves, black anodized threaded aluminum end caps, viton "o" rings and PTFE gaskets. A slide mount accompanies the cell which features a locking mechanism to align and secure the cell. Also included are 1/4" x 1 1/2" long PTFE tubes(2) each with a hose barb end for connecting with laboratory tubing. 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.

A demountable 5cm PTFE gas cell (as pictured below) is also available. Request a catalog for a complete schedule of gas cells and window materials.
