Course Level: Intermediate
Course Description: This session is devoted to NIR spectroscopy, a technique rapidly advancing in practical applications. Nowadays, miniaturization brings it to our home with affordable sensors meant for daily use. Yet, nuances of NIR spectroscopy that set it apart from IR spectroscopy are often misinterpreted. This course presents the fundamental characteristics of NIR spectroscopy and reasons behind its overwhelming application potential. Recent progress in methods and instrumentation decisively changed the application potential and our understanding of NIR spectra. These factors combined together bring a new perspective on NIR spectroscopy, which will be thoroughly discussed during this course. This course is accessible and prepared with care for participants wanting to deepen their understanding of vibrational spectroscopy. Common misconceptions about NIR spectroscopy will be cleared throughout this course and experienced professionals will equally benefit from participating.
Target Audience: The course falls into the keen interest of a diverse community including analytical chemists, scientists, managers and technicians working in the mentioned fields. The accessible form of the course makes it equally suitable for experienced professionals, as well as students and participants beginning their adventure with NIR spectroscopy.
1. Fundamental principles of NIR spectroscopy including unique overview of the physical foundations and how these determine the application potential.
2. The available sensor technology including portable, handheld and miniaturized spectrometers.
3. Overview of how the sensor technology is reflected in its analytical performance and how to manage the optimal performance.
4. Understanding of the procedures and approaches used in analytical applications.
About the Instructor
Krzysztof B. Bec obtained his doctorate (2014) in physical and theoretical chemistry from the University of Wroclaw. His research focused on vibrational spectroscopy, in particular on thin-film IR spectroscopy, and computational methods. He then joined Professor Yukihiro Ozaki team as Postdoctoral Fellow and Research Assistant Professor at Kwansei Gakuin University, Japan; he focused on advancing near-infrared (NIR) spectroscopy and contributed into development of ATR-FUV-DUV spectroscopy and its applications. He continues his work in the field of NIR spectroscopy as FWF Lise Meitner Senior Fellow and Principal Investigator in the group of Professor Christian W. Huck at the University of Innsbruck, Austria. His current research interest focuses on the applications of quantum mechanical methods and artificial intelligence methods in NIR spectroscopy. Krzysztof has contributed as an academic editor of one book, and published 13 book chapters and more than 80 articles resulting in an h-index of 26 based on more than 2100 citations.
