A much discussed issue related to Near Infrared Analysis (NIR) is the necessity of sample preparation. Ground and unground samples of wheat were analyzed to determine how truly necessary it to homogenize samples before NIR analysis.

Increasingly, analysts perform routine analysis where the action islocations of environmental interest, manufacturing suites, crime scenes, loading docks, and packaging facilities through transportable instruments.

The Contaminant Analysis Program compiles a list of common contaminants into one program.

Near Infrared (NIR) spectroscopy is a widely used technique that detects the presence of different chemical bonds through the analysis of optical absorption in the wavelength range 700 to 2500 nm.

FT-IR imaging is a powerful tool for materials characterization.
