Ideal Vacuum offers our LeakFree-IR glass gas cells with a variety of window materials and gas line connections as well as 5cm and 10cm path lengths listed on this website. Not sure of your needs? Call us at (505)872-0037 to discuss your options.
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 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 25.4 mm (1 in.) outer diameter O-ring sealed Pyrex glass cell capped with two 38.1 mm (1.5 in.) diameter windows with
#25 Viton O-rings. Each window is held in place by an industry-standard sized aluminum mounting plate that slots 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 NVacuoTM vacuum manifold components vacuum manifold components
- Minimize waste streams with 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. Dual gas connection stems are especially useful in high-throughput labs that require quick gas sample changeovers to minimizes the time needed between individual gas sample analysis runs. Each of the connection stems includes a ground glass stopcock valve so 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:
Stem Type Options:
- #15 O-Ring Connections
- 3/8 Inch OD Striaght Glass Tube Connections, Perfect For Swagelok® Ultra-Torr® and Our NVacuo O-ring Compression Fittings
- 1/4 Inch OD Striaght Glass Tube Connections, Perfect For Swagelok Ultra-Torr and Our NVacuo O-ring Compression Fittings
- 12/30 Tapper Ground Glass Joint Connections
- 18/9 Semi Ball and Socket Joint Connections
Window Material Options:
Oftentimes, low-pressure IR gas cells require cleaning or replacing the IR windows to remove sample vapor depositions. Our Ideal Vacuum LeakFree-IR gas cells make this chore easy. Each window can be independently removed without disassembling the rest of the gas cell. The only tools necessary are a standard Allen wrench set.
