To commemorate the holiday, LCGC International is proud to present 11 new interviews for you to read, with each interview spotlighting how chromatography is positively contributing to environmental analysis.

Begin your journey below. Happy reading!

Q&A #1

Title: Detecting Drugs and Psychoactive Substances in Influent Urban Wastewater: An Interview with Richard Bade

Summary: Wastewater analysis serves as a surveillance tool for various markers, including lifestyle, exposure, population size, and health indicators. Traditional methods focus on predefined analytes, but face challenges with dynamic substances like new psychoactive substances (NPS). Richard Bade and colleagues have recently published a paper outlining the development and application of a new workflow utilizing the open-source platform InSpectra, aiming to complement targeted analysis and identify geographical spatial trends in wastewater samples across multiple countries.

Interviewee: Richard Bade, Queensland Alliance for Environmental Health Sciences (QAEHS) and The University of Queensland (Australia)

Technique Covered: Liquid chromatography-high resolution mass spectrometry (LC–HRMS)

Q&A #2

Title: A Pyr-GC-Orbitrap-MS Method for Analyzing Microplastics in Air:
An Interview with Silvia Lacorte

Summary: While previous studies have already proposed pyrolysis gas chromatographymass spectrometry (Pyr-GC–MS) methods for microplastic analysis, one of the main constraints with the technique is the lack of standards; method validation procedures to ensure quality control, therefore, cannot be implemented. However, high-resolution mass spectrometry (HRMS) has been shown to provide accurate mass measurements of the different polymers that can overcome limitations such as lack of sensitivity or selectivity, thus offering the possibility to couple a pyrolytic unit in a GC–Orbital trap-MS and increasing the potential for MP analysis in terms of sensitivity, selectivity, precision, resolution, and mass accuracy. In a recent paper, Silvia Lacorte and colleagues share the results of using this method to simultaneously determine the presence of 10 polymers in air.

Interviewees: Silvia Lacorte, Department of Environmental Chemistry at the Institute of Environmental Assessment and Water Research (Barcelona, Spain)

Techniques Covered: Pyr-GC–MS and HRMS

Q&A #6

Title: Magnetic Field-Controlled Chromatography for Fractionation of Rare-Earth Containing Phosphors: An Interview with Laura Kuger 

Summary: Laura Kuger of the Institute for Functional Interfaces (IFG) together with Matthias Franzreb are examining the feasibility of using magnetic field-controlled chromatography to fractionate various rare earth-containing phosphors from end-of-life fluorescent lamps, aiming to develop more effective recycling processes for these valuable materials (1). LCGC International sat down with Kuger to discuss her research and the challenges in scaling up magnetic field-controlled chromatography for industrial applications.
