A glance on novel applications of infrared spectrometry

Infrared spectroscopy with its fast and nondestructive advantages has been qualified for the real-time analysis. Its reliability together with the possibilities for development of portable instruments has provided noticeable progress in its application for several qualitative and quantitative analyzes. Recently, novel instrumental advances such as fiber-optics spectroscopy and operando analysis have opened new doors for on-line monitoring of processes, in-situ evaluation of chemical variations, local determination of chemical structures etc. Nowadays infrared spectrometric investigations are known as informative approaches towards quantitative determination and/or qualitative pattern recognition. However, the noticeable role of chemometric data processing must be also considered for these aims. Chemometric data processing would enable the spectroscopists to deal with the large data set of the spectra in extraction of the most important information and provision of the useful knowledge. A glance on the application of infrared spectrometry in pharmaceutical, petroleum-petrochemical, food and catalyst industries together with introducing its potential for art and cultural heritage evaluations are a part of this wide domain.
