Development of a PLS based method for determination of the quality of beers by use of NIR: Spectral ranges and sample-introduction considerations

Near infrared spectroscopy (NIR) has been used to determine important indicators of the quality of beers, for example original and real extract and alcohol content, using a partial least squares (PLS) calibration approach. A population of 43 samples, obtained commercially in Spain and including diff...
