  • Near Infrared Spectroscopy - Overview | Malvern Panalytical
    NIR converts measured data into actionable information to help optimize processes or improve research Capable of examining irregular surfaces with the same ease as a carefully prepared sample, NIR is non-destructive, and requires little or no sample preparation
  • Why FT-NIR spectroscopy? - Bruker
    What is NIR? Near InfraRed spectroscopy is an analysis method that uses the NIR region of the electromagnetic spectrum (800 - 2,500 nm) It measures the absorption of light from the sample in the NIR region at different wavelengths
