The potential for improvement in the rapidity, cost-effectiveness, and efficiency of sediment analysis by the application of near-infrared reflectance spectroscopy (LAIRS) is recognized. The rapid (< 2 min), non-chemical, non-destructive analytical technique of near-infrared (700 – 2500 nm) spect...
