brilliant spectroscopy Cyclone™ Series - Heatable Long Pathlength Gas Cells The Cyclone™ series of fixed and variable long pathlength gas cells is the ultimate in sampling accessories for measuring the infrared spectra of gases and vapors. Designed for use at a wide range of temperatures and pressures, they are the ideal choice for the analyst who demands superior performance characteristics, high standard specifications and in-built upgradeability. Standard Features • Fixed pathlength • Borosilicate glass body • Ambient temperature operation • Vacuum to 15 p.s.i. operation • Gold mirrors (protected) • Viton® ‘O’ ring seals Based on the White cell principle of multiple light passes between an arrangement of reflecting mirrors, Cyclone™ gas cells are available in three sizes: • Cyclone™ C2 Fixed or variable pathlengths ranging from 0.5m to 2.5m • Cyclone™ C5 Fixed or variable pathlengths ranging from 1m to 8m • Cyclone™ C10 Fixed or variable pathlengths ranging from 2.1m to 10.6m Cyclone™ series gas cells are suitable for operation in all modern FT-IR spectrometers using the Specac Benchmark™ baseplate provided as standard. Cells are available as standard with a borosilicate glass body for operation at ambient temperatures and pressures ranging from vacuum to 15 p.s.i. Protected gold mirrors, internal and external components made from nickel-plated aluminium and stainless steel, and Viton® ‘O’ rings are combined to ensure the highest chemicals compatibility and protection from leaks. • KBr windows • Adhesive-free construction carriages can be used within a single gas cell body to greatly enhance analytical flexibility and reduce costs. Nickel-plated aluminium bodies can be specified for high pressure operation up to 125 p.s.i., and heating jackets / high stability temperature controllers allow operation at temperatures up to 200°C. Purge bellows allow the transfer optics to be used under inert gas atmospheres (e.g. nitrogen) in applications where the elimination of atmospheric H2O and CO2 absorbances is required. Design Excellence • Nickel-plated aluminium components • Vacuum / gas inlet & outlet taps • Purgeable transfer optics box • Benchmark™ series baseplate mounting • CE compliant Optional Features • Variable pathlength mirror carriage • Additional fixed pathlength mirror carriages (all models) Vacuum / gas inlet and outlet taps, KBr windows and a purgeable transfer optics box further enhance this already highly featured range. To ensure perfect operation and freedom from unwanted impurities, a number of unique features have been incorporated into the design and manufacture of the Cyclone™ series. The cells are completely free from adhesives and all of the Viton® ‘O’ ring seals are carefully pre-baked to solvents or out-gassing. Internal screws have small bleed holes drilled into them to prevent any trapped pockets of gas causing sample cross contamination. Unsurpassed Upgradeability • Desiccant storage caps Cyclone’s™ impressive list of optional features means that any analytical challenge can be met. Variable pathlength mirror carriages, and a range of fixed pathlength mirror All Cyclone™ series heated gas cell systems are CE compliant ensuring that they can be operated safely at all times under the recommended conditions. • Purge bellows • ZnSe or CaF2 windows • Nickel-plated aluminium body for high pressures operation (up to 125 p.s.i.) • Heating jacket / controller for high temperature operation (up to 200°C) • Pressure gauge kit • Laser alignment accessory
