Nicolet iG50 FTIR Spectrometer overview

Get the power and sensitivity of a research system with the robustness of an industrial analyzer. The Thermo Scientific Nicolet iG50 FTIR Spectrometer extends the premium performance of the Thermo Scientific Nicolet iS50, our industry-leading R&D spectrometer, onto a rugged, user-configurable FTIR platform designed for industrial applications. The system is highly configurable, compact, and rack mountable. It offers customized solutions for easy integration into your process monitoring systems, making the Nicolet iG50 spectrometer the ideal choice for OEM integration.

The Nicolet iG50 offers high performance to meet the broadest range of demanding applications such as Volatile Organic Compound (VOC) analysis, continuous emission monitoring (CEM) for smokestack emissions, and other chemical process gas applications. With interchangeable optical and sampling interface modules, the Nicolet iG50 system can be customized to fit the unique requirements of industrial process monitoring applications. In addition, the Nicolet iG50 system offers continuity from lab to plant with common formats and workflows enabling lab support when troubleshooting plant issues.

Nicolet iG50 FTIR Spectrometer capabilities

For demanding applications, the Nicolet iG50 provides high spectral resolution needed to isolate sharp gas sample spectral bands from interfering species; an excellent signal-to-noise (S/N) performance allows minimum detectable limits (MDL) of part-per-million or lower, while simultaneously measuring high-concentration components at percent level concentrations. Leverage the spectrometer’s rapid scan capabilities for characterization of high-speed transient events. A compact, stainless steel optics enclosure fits into a standard 19” 6U industrial rack for stable performance in manufacturing settings. Other features of the Nicolet iG50 FTIR Spectrometer include:

  • Dynamic alignment optical controls to maintain bench stability against external vibrations and temperature swings
  • Built-in performance verification and on-board diagnostics to provide bench performance status, both visually and digitally to external DCS systems.
  • Pre-aligned replacement parts, allowing you to perform your own service and maintenance and keep downtime to an absolute minimum
  • A worldwide network of scientists and technical support staff available to support method development, calibration transfer, and warranty service plans


The powerful modular design of the Nicolet iG50 FTIR Spectrometer makes it ideal for a range of demanding industrial process monitoring applications, including process liquid and gas measurements, volatile organic compound (VOC) analysis, continuous emission monitoring (CEM), and at-line film analysis.
