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. 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 removable and easily serviced.
