WorkIR Industrial FT-IR Spectrometer Specifications

Workir™Industrial FT-IR SpectrometerABB Bomem Inc.The Workir is an industrial FT-IR spectrometer designed foron-line process monitoring. Derived from the highly suc-cessful Bomem MB Series of laboratory FT-IR spectrome-ters, it provides spectroscopic performance superior to thatof other industrial units.This instrument is particularly well suited for compositiondetermination of organic process streams in industries suchas refining, petrochemicals, polymers, plastics, chemicals,pharmaceutics, and foods. The Workir is designed for usewith extractive sampling systems. The sample interface iscompatible with Axiom’s Axiot Process FT-IR samplingaccessories.Since the Workir is based on the MB series, you candevelop analytical methods on an MB spectrometer in thelaboratory and transfer them to the Workir without adjust-ment. Methods will also transfer directly from one Workir toanother. The instrument is permanently aligned at the fac-tory. Because of its extreme stability, methods never requireadjustment, even after instrument maintenance.The Workir’s compact, flush-mount chassis fits econom-ically into either rack-mount or wall-mount systems. It isextremely sturdy, and can be operated in any orientation.The Workir comes with CAAP (Continuous AutomatedAnalysis Program), a part of the Bomem family of industrialsoftware. CAAP allows the user to set up fully automatedroutines for run-time analyses. It is perfect for sequencingthe analyses, controlling the sample system valves andpumps, plotting trends, and performing a vast choice ofdata archiving and data communication tasks.CAAP has a comprehensive man-machine interface toaccommodate all categories of users, including operators,maintenance staff, and system designers. It displays bothtext and graphs of measured concentrations, alarms, ana-lyzer status messages, trends, and spectra. It is easily cus-tomized to your specific applications.• Modular • Compact • ReliableABB Bomem Inc. 585 Charest Blvd East, Suite 300 Québec, (Québec), Canada G2E 5S5 Tel.: (418) 877 2944North America: 800 858 FTIRFax.: (418) 877 2834E-mail: ftir@ca.abb.comPRINTED IN CANADA WORKIR 9908(3410) For additional information,visit us on the Internet at www.bomem.comSpecifications• Best resolution: 0.7 cm-1, unapodized• Wavenumber reproducibility:Workir 100 and 104; 0.1 cm-1 at 1918 cm-1Workir 160; 0.04 cm-1 at 7300 cm-1• Wavenumber repeatability: 0.001 cm-1• Calibration transferability test: All NIR instruments will reproduce the absorbancespectrum of toluene (4100-6000 cm-1) in a 0.5 mm cell at 28°C ±1° to within 0.002 A• Signal-to-RMS-noise ratio at peak response istypically 30,000: 1 for the Workir 100 for 1 min scan time, 4 cm-1 resolution, open beam• 100% line repeatability is within 0.1% over the4000 to 550 cm-1 range for MIR models andover the 8000 to 4000 cm-1 range for NIR models, for 2 consecutive scans• 100% line long-term stability does not exceed2% deviation over 16 h over the 4000 to 550cm-1 range in MIR models and over the 8000 to4000 cm-1 range in NIR models• Resolution is selectable from 1 to 64 cm-1,apodized, in steps of 2 X• Scan Time: 3 s with DTGS, 1.2 s for fast detectors, at 4 cm-1 resolution• Beam diameter at beam stop: 2.5 cm• Maximum beam divergence: 90 milliradians• Overall dimensions: 17 1/2 in.
