Prof. Dr. Detlef Günther - www.analytica.ethz.ch - graduated from the Martin-Luther-University of Halle-Wittenberg (Germany) in 1987. His PhD thesis focused on “The Interpretation and Optimization of Sampling and Transport” as well as “Calibration for Quantitative LM-ICP-OES”. After post-doc periods at Duisburg University (Germany), the Institute of Plant Biochemistry in Halle (Germany), and the Memorial University of Newfoundland (Canada), he joined Prof. C.A. Heinrich in a research program on "Micro Analytical Developments for the Analysis of Fluid Inclusions Using LA-ICP-MS" at the Institute of Isotope Geology and Mineral Resources at ETH (SFIT) Zurich (Switzerland). His introduction of a new homogenized excimer laser ablation system (ArF, 193 nm) has contributed significantly to improving the applicability of laser ablation technique. One of his major contributions to gemology is his published pioneer work on "Quasi-nondestructive Fingerprinting of Sapphires Using LA-ICP-MS", which led to an extensive study of various gemstones. In 2003, Dr. D. Günther became Associate Professor at the Laboratory for Analytical Chemistry at ETH (SFIT), in Hönggerberg (Switzerland).
