FFM Series - Multipass Gas Cells Brochure

PS-FFM-200 Rev. A (9-13-13) FFM-200 Series FIBER-OPTIC COUPLED MULTI-PASS GAS CELLS Robust process analysis cells for use with coherent spectrometers. FFM Series process gas cells have been design to take maximum advantage of the spatial coherence which characterizes the new generation of spectrometers based on tunable lasers. Two key elements of the design are a high degree of mechanical precision combined with robust materials (fused silica and stainless steel) in contact with the process stream. These are combined with an optical design which allows the cell to be aligned while assembled by using a fiber-optic coupled visible laser source. As a result, an FFM cell can be disassembled, cleaned with common solvents, reassembled, and realigned in minutes. This makes the FFM highly suitable for use in applications such as dryer off-gas monitoring where upset conditions may occasionally coat the interior of the cell with powders or other contaminants. Features: Extreme chemical resistance Suitable for high temperatures and pressures Can be easily cleaned and reassembled Easy alignment when fully assembled No delicate optics in contact with process stream Choice of pathlength per pass FFM-200 SPECIFICATIONS: Number of Passes: 2 and 6 (selectable) Pathlength per Pass 1 meter, standard Optical Material in Contact with Process Fused Silica Material of Construction: PTFE coated 316 stainless steel Seals: Kalrez™ 6375 O-rings Alignment: Laser alignment source provided Provision for cleaning: End assemblies can be removed and reinstalled while requiring only minimal alignment. 1451-A Edinger Ave., Tustin, CA 92780 Tel: (949) 757-9300 · Fax: (949) 757-9306 Web: www.goaxiom.com · Email: info@goaxiom.com
