Spectroscopic Techniques for Sample Qualification

The electromagnetic spectrum can be divided into distinct ranges from low-energy long-wave radiation to high-energy short-wave X rays and beyond (Fig. 3). From a spectroscopic point of view, the basis of these different ranges is the nature or type [Pg.402]

The basic steps involved in identifying a sample using NIR will be illustrated using the SIMCA method, which is one of the popular methods for product ID. The [Pg.404]

SIMCA method relies on a pattern-recognition technique called principal component analysis (PCA). [Pg.405]
