Dr. Jochen Vogl is working in the field of elemental and isotope analysis by applying mass spectrometry. Core applications are isotope dilution mass spectrometry and isotope analysis of specific elements. The production and certification of isotope and matrix reference materials is another core application. Following metrological principles is key, when aiming at reliable analytical results. Current projects are Certification a new Mg isotope reference material; B isotope fractionation in bell pepper
