Near Infrared (NIR) analysis is a spectroscopic technique, which makes use of the naturally occurring electromagnetic spectrum. The NIR region is the area of the spectrum defined by wavelengths as between 700nm and 2500nm. FoodScan™ Dairy Analyzer is working with NIR Transmission in the region 850-1050 nm.
The NIR area has proved to be the ideal spectral area to make natural product and chemical property measurements of liquid, solid, slurry or gaseous samples. All of the NIR products are based on dispersive grating based Monochromator's as they afford the user the highest level of signal-to-noise available in any commercially available NIR product. The advantage of this boost in performance is better precision in an application and the capability to measure high scattering and multi-phase matrices. The combination and overtone bands in the NIR are much less intense than the primary bands in the Mid IR, therefore, giving NIR measurements larger dynamic range and the capability to utilize various path lengths for different applications. Other advantages of the NIR spectral region are; the latitude of materials that are available for sampling, so not to impede with the measurement, such as quartz glass and polyethylene bags for lab sample analysis and for in-line process measurement, and the use of low cost fiber optics and probes. NIR analysis is a safe and non-destructive technique. Typical molecules we analyze for in the NIR include CH, OH and NH and related chemistries regarding constituents.
