Specac | ProCell - Process Flow CellsOptimized construction materialsRugged. Robust. Reliable.Process flow cells are designed to withstand therigors of process and environmental conditionswhile maintaining continuous measurementstability. The choice of construction materials isan important consideration to ensure materialcompatibility with a range of substances in theprocess stream, and durability to the temperatureand pressures of operation - this often goesbeyond standard operating conditions, andincludes aggressive cleaning regimes andextreme weather conditions.Cell body material:Specac ProCell process flow cells aremanufactured from a range of materials, chosento ensure optimum chemical compatibility andenvironmental durability. Typical materials includeStainless Steel 316L, Duplex Stainless Steel,Hastalloy© C276, Zirconium, or Titanium, butothers are available upon request.Window material:Sapphire windows are used as standard toensure the highest level of process cell durability.With outstanding thermal characteristics, coupledwith exceptional abrasion resistance – secondonly to diamond – and strongly resistant againstcorrosive process fluids, sapphire is a clearmaterial of choice for process flow cell windows.Standard sapphire substrates offer excellenttransmission characteristics from the UV to 5microns; for specific UV applications, UV gradesapphire is available. As sapphire is able to bepolished to a high degree, it is less prone tofouling than other lesser materials.Seal material:Process flow cells contain a seal between theoptical and mechanical components, and theintegrity of this seal is often critical to the reliabilityof the cell. Specac offers a wide variety of sealoptions to meet a broad scope of customerneeds. These include chemically inert perfluoroelastomers(such as Kalrez© or Chemraz©), orgold diffusion bonding for the most demandingapplications.For added peace of mind, perfluoroelastomerseals may be incorporated in a unique dual sealarrangement to guard against the unlikely eventof window seal failure. With the aid of complexmodeling software, Specac application engineerscan predict the behaviour of the seal under a widevariety of conditions that may be experiencedduring its lifetime.Optical fiber cablesDelivering light to the point of measurement.Specac ProCell process flow cells are compatiblewith a range of optical fiber cables, with coresizes of up to 600 microns diameter. Theseshould be selected by the user to be appropriatefor the application. For instance, water-freeoptical fiber is typically used for NIR applications,while special UV-grade optical fiber should beused if enhanced UV transmission is needed.Optical fibers should also be appropriately coatedfor the temperature experienced at the point ofconnection to the process flow cell: polyimidecoatedor metal-coated fibers are recommendedfor higher temperature applications. Specacfollows the industry standard by using the widelyavailable and popular SMA 905 style of fiberconnector to interfaceoptical fibers with theprocess flow cell.brilliant spectroscopy www.specac.com
Specac | ProCell - Process Flow CellsAdded featuresTell tale leak ports, fiber termination hoods, cleaning ports.A wide range of added features are offered bySpecac to further enhance the performance ofour ProCell process flow cell product range.For instance, seal leak warning ports can beincorporated for additional process security, andcells can be specified with a cleaning port to alloweasy in-situ cleaning of the windows without theneed to remove the cell from the processenvironment. Furthermore, protective metalhoods (to I.P. 65 rating) can be fitted over thefiber connections to relieve strain from the fiberconnector, to guard against accidental damageat the process cell port, and prevent ingressionof moisture and dust/dirt.Range of Process CellsLiquids. Vapours.ProCell Vortex Liquid Phase Process Flow Cell:Specac's ProCell Vortex liquid phase process cell isdesigned to sample industrial liquid streams bymeans of UV/Vis or NIR. These applicationsusually involve optical pathlengths of 1.0 - 10mm.Typical specifications are 0 to 400°C and vacuumto 1500 psi.ProCell Typhoon Gas/Vapour Phase Process Flow Cell:Specac's ProCell Typhoon process cell isdesigned to sample industrial gas / vapour phasestreams by means of UV/Vis or NIR. The gas orvapour stream is sampled through a preset, fixedpathlength (20, 30, and 50 cm available asstandard), and typical specifications are 0 to 280°Cand vacuum to 1500 psi.www.specac.com
