The Speakers
John Entwisle has over 30 years of analytical chemistry experience gained in a wide range of areas including petroleum products and gas mixtures analysis. He joined LGC in 1988 where he gained experience in pesticide residues, food, alcoholic beverages, consumer products analysis and the preparation and certification of matrix reference materials. He obtained a Bsc (Hons) in Chemistry in July 1991 from Kingston University, Surrey and has subsequently achieved chartered chemist status at the Royal Society of Chemistry. Since 2001 he has been developing methodologies as part of research projects for the determination of species/total elements in food/environmental sample types at a metrological level in order to improve measurement capabilities. Where possible this has involved using isotope dilution techniques, including species-specific IDMS to provide primary reference values for the certification of reference materials and to participate in international inter-laboratory comparison studies. He specializes in the development of extraction and LC separations of inorganic species.
Dmitriy Malinovskiy graduated from St-Petersburg University in 1996 and then worked firstly as a researcher and then as a senior researcher in the Russian Academy of Sciences (RAS), obtaining a PhD-degree there in the area of environmental science. In the period from 2001 to 2006 he worked in Lulea University of Technology, Sweden, where he obtained a PhD-degree in the area of Applied Geology. He then worked as a postdoctoral researcher in the laboratory for Chemical Metrology of the Institute for National Measurement Standards, Canada, and at the Department of Analytical Chemistry, Ghent University, Belgium. He joined LGC in 2011. The focus of his work has been on the development of new and improved methods of isotope ratio measurements and delivering research projects in the areas of analytical chemistry and environmental geochemistry.
