The Long Path Mini Gas Cell is a multiple-pass long path cell with a small footprint that permits the spectroscopist to vary its pathlength from 1.2 meters (at 8 passes) to 6.0 meters (at 40 passes). An externally mounted knob at the end of the cell allows variation of the pathlength while the sample is in the cell. The cell volume is 0.5 liters. The overall cell dimension is approximately 14” in length and 3” wide and the borosilicate glass pipe is 6 cm in diameter. See the general description of fixed pathlength long path gas cells for descriptions of the optical system, transfer optics, mirrors, windows, hardware and valves.
