Stir-Bar Sorptive Extraction of Trace Organic Compounds from Aqueous Matrices

In this interview, we asked Hemanth Kumar Chanduluru from the SRM Institute of Science and Technology in Kattankulathur, India, multiple questions regarding sustainability in analytical separation methods.

Food 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.

As LCGC International celebrates Earth Day, we spotlight the current chromatographic research that is advancing environmental analysis and sustainability efforts. In this interview, we spoke to Daniel Armstrong, professor of chemistry and biochemistry at the University of Texas at Arlington, about his work using mathematical strategies to minimize analytical method greenness scores (AMGS) in HPLC enantioseparations.

To commemorate the celebration of Earth Day, LCGC International sat down with Laura Kuger of the Institute for Functional Interfaces (IFG) and the Karlsruhe Institute of Technology to talk about her latest research in using magnetic field-controlled chromatography to fractionate rare earth-containing phosphors.

In this written interview with Dwight Stoll, LCGC Columnist and Professor of Chemistry at Gustavus Adolphus College in St. Peter, Minnesota to address the pressing issues of sustainability and environmental awareness in separation science.

In this interview, Angela Calderón of Auburn University discusses the importance of using more environmentally friendly analysis techniques.
