The combination of the FT analysis method and the NIR spectrum combine to make FT-NIR a very useful online analytical tool. The use of the FT technique allows for instantaneous analysis of the entire spectrum of a broadband light source, rather than having to scan across the spectrum of interest or use only a single point of the electromagnetic spectrum for analysis. This is ideal for providing detailed analytical information of continuously flowing or changing processes. Although not as sensitive as mid-IR spectroscopy, NIR spectroscopy allows for deeper penetration of the sample, and is better for bulk materials.
Online FT-NIR is used most heavily in refineries and general chemical facilities due to its strength in the analysis of petrochemical compounds. A rapidly growing niche is in the development of alternative biofuels. The global market for process FT-NIR is well over $20 million annually, and is expected to see mid-to-high single-digit growth.The foregoing data was based upon SDi's Market Analysis & Perspectives (MAP) report program.
