IR spectroscopy is thus an absorbance method where different molecular structures will absorb light at different wavelengths. In general, IR spectroscopy provides stronger absorbance and sharper peaks than NIR spectroscopy does. However, near-infrared spectroscopy is generally preferred for PAT because NIR...
Various works concerning the use of NIR in the evaluation of raw materials, such as barley, malt, hop, and yeast, are also summarized here. The implementation of NIR sensors for the control of malting and brewing processes is also highlighted, as well as the use of NIR for quality ...

500 to 4000 cm-1 or more. NIR spectrometers use high precision diode array detectors and silicon or lead-sulfide CCDs, which are generally more sensitive. Because of the diverse range of applications for NIR spectroscopy, these NIR spectrometers can be reconfigured to accommodate both liquid and...
Analytical techniques employed so far, including mass spectroscopy, NMR spectroscopy and separation techniques, are all destructive, expensive and time-consuming, and therefore they are not really suitable for high-throughput quality control. For this purpose, near-infrared (NIR) offers novel highly ...
NIR spectroscopy is being widely adopted for sodium analysis of many food products such as wine and cheeses and human diets, among others. NIR technology is rapid, accurate, low cost (does not require sample processing), nondestructive, and more environmental respectful when compared with other ana...
