The 2010 MultiGas™ Analyzer employs a 2102 Process FTIR Spectrometer, On-Line's patented, high throughput sampling cell, applications specific analysis software, and a precalibrated, transferable reference library. On-Line's spectrometer is the world's fastest, most sensitive and most stable process FTIR available. The spectrometer is permanently aligned and requires no adjustments. The spectrometer obtains high resolution infrared spectra which are compared to the quantitative library reference spectra for high sensitivity and accurate analysis of most gases and vapors. Our FTIR multi-gas analyzers have significant advantages when compared with competing gas analysis methods in speed, sensitivity, ease and permanence of calibration, quantitative accuracy (especially in complex mixtures), and low maintenance requirements.
2102 Process FTIR Spectrometer
The software includes automatic corrections for gas temperature and pressure variations. Self-diagnostics are provided by an internal microprocessor. A complete spectrum can be obtained within 1 sec, Fourier transformed within 200 msec, and analyzed within 1 sec. The system is fully automated and can be operated by minimally trained personnel. The software allows for simultaneous measure and display of more than 20 gas specie concentrations.
20/ 20 Long Path Aberration- Correcting Gas Cell
The 2102 Process FTIR Spectrometer is a compact and rugged instrument designed specifically for process and environmental monitoring. The spectral resolution is user defined from 0.5 – 128 cm-1. It can operate in hostile environments with high vibrational and temperature immunity. An advanced high speed data processor provides low noise infrared spectra.
The FTIR can be coupled to a variety of gas cells. The Model 20/20™ 5.26 m or 21.04 m path gas cell with non-spherical, aberration-correcting mirrors provides more than twice the throughput of a standard White Cell. Single pass gas cells between 1 cm and 30 cm can be used for corrosive gases. Robust quantitative analysis software, performed on a Pentium PC, can simultaneously analyze more than 20 gases.

The 2010 may be used to control a process, or record and employ auxiliary sensors. The user may customize the instrument configuration using National Instruments LabVIEWÔ for FT-IR. As shown in the example, graphical programming is performed by linking function icons on the screen. LabVIEW’s library of icons for instrument interfacing and display have been augmented by On-Line’s library of FTIR control and quantitative analysis functions.

The user interface contains a menu to select quantitative data displays, diagnostic routines, or spectral information.
The Multi-Gas Setup Utility is used to select the analysis gases and files for computed results, spectra and interferograms. The user can manually add temperature and pressure data or have it read from the sensors.
During data collection the MultiGas software continuously acquires, processes and computes the concentrations for gases that are selected. The data may be displayed as the current spectrum, a table of concentrations, time lines or spectral residuals. Once data have been collected they may be reprocessed at anytime using the same or different calibration.
Spectrometer diagnostics are continuously updated and provide the user with quick access to the instrument’s operating condition.
