Handheld NIR Spectroscopy: A RapidOn-Site Technique for Quality Controland Protection against Counterfeitingin the Materials and Life Sciences

Heinz Wilhelm Siesler, University Duisburg-Essen, Germany

Wednesday, March 6th 2024, 4:00 – 5:30 pm

The presentation considers the rapid development of miniaturized handheld NIR spectrometers over the last decade and provides an overview of current instrumental developments and exemplary applications in the fields of materials and life sciences control as well as environmentally relevant investigations. Care is taken, however, not to fall into the overoptimistic narrative of some direct-to-consumer companies, which has raised unrealistic expectations with full-bodied promises, but has harmed the very valuable technology of NIR spectroscopy, rather than promoting its further development. Particular attention is paid to potential applications that will enable a clientele that is not necessarily scientifically trained to solve quality control and authentication problems in everyday life with this technology in the not-too-distant future.
