At HTC-18 in Leuven, Executive Editor of LCGC International, Alasdair Matheson, spoke to Jan Christensen from the University of Copenhagen about his presentation entitled: “Quantitative Non-Targeted Screening of Environmental Samples: Endless Possibilities – But With Caution."
Jan H. Christensen is a Professor in Environmental Analytical Chemistry. He is the leader of the Analytical Chemistry group, Faculty of Science at the University of Copenhagen, Denmark and heads the Research Centre for Advanced Analytical Chemistry (RAACE). His group develops analytical methods and new tools to handle and process complex multidimensional chromatographic data. The main application areas are currently suspect- and non-target screening of organic and inorganic contaminants in waste-, surface-, and drinking water; as well as sustainable fuels; plant–microbe interactions, and foods. Jan has authored and co-authored more than 160 peer-reviewed papers and book chapters on these topics, are (co-)responsible for five courses in analytical chemistry, and has supervised over 80 BSc, MSc students, and PhD students ORCID : 0000-0003-1414-1886. He is an active member of LCGC international’s editorial advisory board (EAB).
Jan discussed the following topics:

The Future of Digital Method Development: An Interview with Anne Marie Smith
September 5th 2024Following the HPLC 2024 Conference in Denver, Colorado, LCGC International spoke with Anne Marie Smith of ACD/Labs about the new ICH Q14 guidelines and how they impact analytical scientists and their work.
Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
