Advanced Near IR Algorithm Compensates for Spectral Features Related to Changes in Sampling Vials
Low cost, disposable culture tubes are often used for the rapid analysis of liquid samples by Fourier transform near-infrared spectroscopy
An evaluation of tubes from two suppliers revealed significant differences in the FT-NIR spectra obtained from the empty tubes. A quantitative analysis technique developed at Sandia National Laboratory provides a simple way to augment a classical least squares.
