Abstract
As a spectroscopist, one rapidly learns that obtaining a spectrum of a sample is only part of the work. Many times the real challenge comes in interpreting the spectrum. In correlation transform spectroscopy, commonly referred to as near-infrared analysis, a large emphasis is placed on the data interpretation phase. To make the spectral results intelligible to the analyst, near-infrared analysis correlates a series of spectra with the known analyte concentration. This correlation transforms the spectra so that the relationship between the analyte and the spectra is displayed. This process can be extended to deduce the spectrum of a pure component from those of mixtures, or to deduce the analyte concentration in an unknown sample. Interestingly, near-infrared analysis has shown that surprisingly little spectral resolution is required to quantitate many analytes. Thus, instrumentation designs are being developed which make use of very broad filters made of polymers or other materials. These instruments provide spectral information in much the same way that the eye does.
