    The G-2 Gas Cell is for analysis of pure gases or gas mixtures in which component gases are present at concentrations of 5 percent or more. The G-2 Gas Cell has a fixed pathlength of either 5cm or 10cm. The windows of the cell are easy to remove for cleaning, making the G-2 ideal for working with wet or reactive gases that have a tendency to fog or attack the window material.

  • sp51_dem-beta-gc-shade

    The demountable Beta Gas Cell comes complete with a 10cm or 5cm Pyrex Cell body, cell mount, 2 Viton® O-rings or gaskets, 2 PTFE gaskets, and 2 septa, but without windows. (Windows and gaskets can be ordered separately). The window size is 25mm x 4mm. When assembled, the cell will be gas tight and operable at both reduced or positive pressures. Filling of the cell is conveniently handled with a gas tight syringe (ICL Part no. 0009-609).

  • Mercury Group

    Short Path Gas cells are useful for pure gases and, generally speaking, for concentrations of not less than 100 ppm. Cell utility for various ppm concentrations is dependent not only on path length, but also on the absorbance characteristics of the sample. Feel free to consult with us on these and any other issues concerning selection of an appropriate gas cell.
    ICL's Gemini™ gas cell line begins with our Mercury™ short path length single pass gas cells constructed of electropolished 316 Stainless Steel, available in standard path lengths of 1cm, 2cm, 3cm, 5cm, 10cm and 15cm. Custom path length cells for a variety of applications are also available.
    These robustly constructed gas cells are ideal for specialty gas analysis, because they are leak tight and capable of high vacuum performance exceeding 1 x 10-8 Torr, and they also can be made pressure-safe with appropriate window material and thickness selection. Each Mercury™ cell is individually helium leak tested or hydrostatically tested and a test certificate can be supplied with any cell for $299.00 (Part No. 0009-9281).
    Mercury™ cell configurations include base plate mounted, slide mounted and heated versions with temperature controllers. Purge maintaining connectors or couplers extending from the cell body to the sample compartment walls are standard on many base plate mounted models and purge gas connections are an available option. A wide variety of window materials can be used. Wedged windows are available to limit fringing. Instrument specific spectrophotometer interfaces are available.
    Mercury™ cells feature high-vacuum welded gas fittings without valves comprising the sample inlet and outlet to maintain the leak-free integrity of the cell and assure high vacuum performance. Inlets and outlets comprise a Swagelok® VCR gland, a VCR female nut, a male VCR nut and a 1/4" Swagelok® adapter. Valve kits are available.
    Several common Mercury™ cell configurations are shown, but custom configurations are available upon request. Prices do not include windows, which can be selected from our transmission window price list. RFQ for wedged windows. Cell mounting and other hardware, exclusive of the cell body material and valves, is black anodized aluminum.

  • Venus

    Venus™ cells are small to moderate volume long path gas cells designed for all purpose use in industrial and research applications. The cell design has improved significantly over the years with such advances as multilayer proprietary gold mirror coatings, improved purgeable transfer optics, and instrument specific base plate mountings. All Venus cells are fitted with Swagelok® 1/4" or 1/8" tube fittings to which valves, hose barbs or compression fittings can be attached. SS Swagelok® Valves are standard on the models listed.
    Venus™ cell configurations include ICL's popular Ultra Mini Cell which measures 3" x 3" x 8" (3 meters fixed path length, 200cc volume), the Long Path Mini Cell (variable path length to 5 meters, 0.5L volume) and fixed and variable path length cells ranging from 4.8 to 8 meters. Heatable, laser aligned, base plate mounted and other custom configurations of Venus™ cells are available. Instrument specific interfaces are available for base plate mounted cell configurations.
    Several common Venus™ cell configurations are shown, but custom configurations are available upon request. Prices do include KBr windows, but optional windows can be selected from our transmission window price list. RFQ for wedged windows to limit fringing a/k/a channeling. Cell mounting and other hardware, exclusive of the cell body material and valves, is black anodized aluminum. Fittings and Valves are SS Swagelok®. All cell bodies are borosilicate glass. Mirrors are GemGold™ multi-layer gold coated, removable and easily serviced.

  • Earth

    Gemini™ Earth™ glass bodied long path gas cells are, like Venus™ cells, classic Hanst cells, but with larger volumes and longer path lengths. Pathlengths range from 10 to 20 meters and volumes range from 2 to 8 liters.
    All Earth™ cells feature SS Swagelok® valves, multilayer gold coated mirrors, borosilicate glass bodies, transfer optics and base plate configurations to fit most spectrophotometers, and black anodized aluminum hardware. Earth™ cells use 1/4" SS flow tubes and Swagelok® connections. All variable path length cells incorporate a laser alignment device with a 6 volt DC power supply for path length verification based on the number of passes made through the cell.
    Several typical Earth™ cell configurations are shown, but custom configurations are available upon request. Prices do include KBr windows, but optional windows can be selected from our transmission window price list. RFQ for wedged windows to limit fringing a/k/a channeling.

  • Mars

    For applications that demand high performance, durability, reliability, simplicity, dependability and serviceability, Gemini™ Mars™ gas cells are the solution. Mars™ long path cells address the most demanding gas sampling requirements of industrial and field deployed FTIR and IR instrumentation with a robust series of metal bodied gas cells with electro-polished stainless steel or electro-less nickel plated aluminum bodies that outperform any gas cell on the market.
    A key factor ensuring the durability and serviceability of each Mars™ cell is the use of stainless steel mirrors. These mirrors are extremely durable and they can be reconditioned many times at modest cost, thereby extending the service life of each Mars™ cell for many years. All mirrors are coated with our proprietary Gemgold™ multilayer gold coatings to insure the highest possible performance in demanding environments. Stainless steel optics are inherently superior to diamond turned aluminum mirrors, from the standpoint of longevity and serviceability. While 316 stainless steel tends to resist the corrosive effects of reactive gases, aluminum tends to react with many gases making aluminum subject to corrosion and therefore an inferior optical substrate.
    A more effective low cost option to aluminum mirrors is gold coated glass mirrors, which can be special ordered on Mars™ at a discount to the prices of cells with stainless steel mirrors. Mars™ cells feature modular designs with interchangeable and reconditionable components, enabling us to deliver gas cells that are both versatile and serviceable. Metal bodies and cell hardware can be constructed from many materials. Cells from materials such as stainless steel (passivated or electro polished), pure nickel, nickel coated aluminum, black anodized aluminum, and FEP or PTFE coated aluminum are all available and can be configured to user specifications.
    Mars™ gas cells can be configured for high vacuum exceeding 1 x 10-9 Torr and high pressure applications. Each Mars™ cell is individually helium leak tested or hydrostatically tested and a helium leak test certificate can be supplied with any cell for $299.00 (Part No. 0009-9281).
    Mars Cells can be configured with heating jackets and with user programmable temperature and pressure control and monitoring options.
    Several common Mars™ cell configurations are shown, but custom configurations are available upon request. Prices include KBr windows, but other materials can be selected from our transmission window price list. RFQ for wedged windows to limit fringing. All Mars™ cells use 25 x 4mm windows. Cell mounting and other hardware, exclusive of the cell body material and valves, is black anodized aluminum.
