Our Ideal Vacuum infrared LeakFree-IR glass gas cells are designed to fit in all IR and Fourier Transform Infrared (FTIR) spectrometers. They are perfect for collecting low pressure IR spectra of gas phase samples; typically, vapor pressure of 1 to 10 Torr is all that is needed inside these 10 cm long gas cells to get a beautiful IR spectrum.

It is very important when shopping for a new IR gas cell that you consider how "Leak-Free" the gas cell will be. No one wants to add 10 Torr or so of sample vapor pressure to their low-pressure IR cell and see the pressure continuously rise as room air leaks in around the window seals! Our LeakFree-IR gas cells are the most "Leak-Tight" models available: the cell itself consists of a 25.4mm (1in.) outer diameter O-ring sealed Pyrex glass cell sandwiched between two 31.8mm (1.25in.) diameter windows with #25 Viton O-rings. The assembly is held together by an industry-standard stainless-steel frame and mounting plate assembly that slides into a wide assortment of spectrometer cassettes. Each of our LeakFree-IR low pressure gas cells are assembled and helium leaked tested to ensure that they are a quality leak-tight product before they are shipped to our customers.

Benefits of using our LeakFree-IR Low-Pressure Gas Cells:

• They are Leak-Tight
• Each cell is helium leak tested for quality
• Limit contamination of sample vapor with atmospheric gases
• Limit reactions of sample vapor with atmospheric gases
• Limit spectral overlap from atmospheric gas bands (e.g., H2O and CO2)
• Recover pure gas sample vapor from IR cell using our NVacuo vacuum manifold components
• Minimize waste streams, no need to evacuate gas sample vapors into the vacuum pump.

Each of our LeakFree-IR low-pressure gas cells are designed with dual gas connection stems (one for sample addition and the other for evacuation of the gas cell), allowing for easy and leak-free connections to gas fill and vacuum lines. Having dual gas connection stems is especially useful in high-throughput labs that require quick gas sample changeovers to minimizes the time needed between individual gas sample analyses runs. As added value each of the connection stems includes a ground glass stopcock valve so that the low-pressure sample vapor can be sealed inside our LeakFree-IR gas cell and isolated from the vacuum and gas fill lines. Our LeakFree-IR gas cells can be ordered with a variety of standard gas stem connection types:

Option 1, Ideal Vacuum LeakFree-IR Gas Cell Connection Stem Types:

• #15 O-Ring Connections
• 3/8 Inch OD Straight Glass Tube Connections, Perfect For Swagelok Ultra Torr and Our NVacuo O-ring Compression Fittings
• 12/30 Taper Ground Glass Joint Connections
• 18/9 Semi Ball and Socket Joint Connections

Option 2, Ideal Vacuum LeakFree-IR Gas Cell Window Material Types:

• CaF₂ Calcium Fluoride Windows
• BaF₂ Barium Fluoride Windows
• KBr Potassium Bromide Windows
• NaCl Sodium Chloride Windows
• KCl Potassium Chloride Windows

Oftentimes, low-pressure IR gas cells require cleaning of the IR windows to remove sample vapor depositions. Our Ideal Vacuum LeakFree-IR gas cells make this chore easy. When cleaning or changing window materials, a single flat head screwdriver is all that is required to dismantle the glass cell from the stainless steel holder. The built-in plate alignment makes accurate re-assembly fast, easy, and secure.
