Course Description
Miniaturization of Raman, mid-infrared (IR) and near-infrared (NIR) spectrometers is recently undergoing a dramatic development and numerous companies currently push new instruments with a broad variety of operation principles on the market. The reduction in size, however, must not lead to compromises in measurement performance and precision and the handheld instrumentation will only have a real impact on quality control if Raman, IR and NIR spectra of comparable quality to laboratory spectrometers can be obtained. The presentations on the building principles, performance parameters and real-life applications of state-of-the-art handheld systems to a broad diversity of topics will demonstrate the advancement of these spectrometers for on-site and in-the-field measurements. The discussed qualitative and quantitative case studies range from pharmaceutical to polymer analysis via environmental and geological investigations to food authentication and will enable the participants to assess which instruments suit best for their on-site applications. Finally, the industrially very important issue will be highlighted how calibration models (PLS, PCA) developed with the spectra of laboratory spectrometers can be further utilized with spectra measured in the format of handheld spectrometers by applying a novel transfer algorithm.

Target Audience
The course addresses R&D and laboratory managers, researchers, analytical chemists, spectroscopists and laboratory technicians from chemical, polymer and pharmaceutical industry as well as environmental, food and law enforcement institutions with interest in quality and process control by on-site and in-the-field measurement of vibrational spectra.

Course Outline
Key Topics:
Condensed introduction to the principles of qualitative and quantitative Raman, IR and NIR spectroscopy
Short historic overview on the miniaturization in vibrational spectroscopy
Building principles of the state-of-the-art handheld Raman, IR, and NIR spectrometers
Discussion of qualitative and quantitative application examples in chemical, polymer, textile and pharmaceutical quality control.
Furthermore, such typical on-site examples as bitumen analysis for road construction work, hydrocarbon contamination in soil, polymer recycling, and authentication of food will be addressed. Life demonstration of different instruments will enable participants to assess the measurement performance of available handheld spectrometers and evaluate the possibility of their implementation for on-site quality control routines.

Course Instructor's Biography
Heinz Siesler is a Professor of Physical Chemistry at the University of Duisburg-Essen, Germany, since 1987. His main research interests focus on the application of vibrational spectroscopy to chemical and polymer research, analysis and quality control. He has written more than 230 publications (including four monographs) in this field of research and presented more than 250 lectures worldwide. He received the 1994 EAS Award, the 2000 Tomas Hirschfeld Award and the 2003 Buechi Award in near-infrared spectroscopy and he is a Fellow of the Society for Applied Spectroscopy. Prior to his present academic position he gained extensive industrial experience as section head in molecular spectroscopy and thermal analysis from 1974 to 1987 in the Corporate R&D Department of Bayer AG, Germany. He also worked as lecturer at the University of the Witwatersrand, Johannesburg, South Africa (1972-1974) and as post-doc at the University of Cologne (1970-1972), Germany, after receiving his PhD in Chemistry from the University of Vienna, Austria, in 1970. Heinz Siesler is consulting for numerous instrument and chemical companies. The test of miniaturized handheld vibrational spectrometers is a special research focus over the last six years.
