Kevin A. Schug is a Full Professor and Shimadzu Distinguished Professor of Analytical Chemistry in the Department of Chemistry & Biochemistry at The University of Texas (UT) at Arlington. He joined the faculty at UT Arlington in 2005 after completing a Ph.D. in Chemistry at Virginia Tech under the direction of Prof. Harold M. McNair and a post-doctoral fellowship at the University of Vienna under Prof. Wolfgang Lindner. Research in the Schug group spans fundamental and applied areas of separation science and mass spectrometry. Schug was named the LCGC Emerging Leader in Chromatography in 2009, and most recently has been named the 2012 American Chemical Society Division of Analytical Chemistry Young Investigator in Separation Science awardee.

In April 2020, on the heels of the pandemic shutdown, the price of crude oil fell to a negative value for the first time ever. The shutdown hit many oil and gas companies hard. But while companies lick their wounds and decide their next moves, an important concept called environmental and social corporate governance (ESG) has come greater into focus.

Jasmin Zboron joined the Gerstel Analytical Services department in 2015 as Application Specialist, after completing her B.Sc. Following projects on determining priority contaminants in water, her main focus is currently on GC/MS sample preparation and application development.

A highly sensitive method for quantitative determination of contaminants in surface waters, with and without particulate matter, was tested using stir-bar sorptive extraction (SBSE).

Jennifer Lüber is currently the Product Specialist for Titration/TitrIC at Metrohm AG in Switzerland. She finished her apprenticeship as a Lab Technician at Metrohm AG in 2014. Afterwards, she was involved in projects related to column development, and worked in the laboratory for a short time at Metrohm UK. In 2015, Jennifer returned to Metrohm AG to join the competence center for titration, eventually taking responsibility for the TitrIC systems in 2018. Jennifer received her professional bachelor’s degree in business process management in 2019.

Waldemar Weber started his studies as a chemist in 2005 at the University of Münster, Germany. There, after graduating as a chemist, he achieved his Ph.D. in 2011 and completed a postdoc in 2013 at the Münster Electrochemical Energy Technology (‘MEET’) Research Center. From 2012 to 2013 he was employed as an Application Specialist at JAS in Moers, Germany. In November 2018 he joined Shimadzu Europa as Product Manager for GC–MS.

Exploring a new TD method capable of simultaneous analysis of compounds with a wide range of boiling points, high sensitivity, and high restore rates.

Analysis of Volatile Organic Compounds in the Environment Using TD-GC–MS

A hybrid HILIC–ion exchange column was used for the analysis of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) compounds in environmental waters. This direct injection LC–MS method enables simultaneous measurement of ultrashort- chain, alternative, and legacy PFAS in potable and non-potable waters.

A comprehensive monitoring protocol has been developed using GC–MS/ECD in selective ion monitoring (SIM) mode, with injection performed by solid-phase microextraction (SPME) and headspace (HS). This single system has been configured to analyze for all taste and odor (T&O) compounds in Standard Method 2170, with minimal changing of columns, injectors, or SPME fibers between methods.

This article explores the role of SPE sorbents for analyte recovery rates and method accuracy to develop clean samples for analysis and to reach lower limits of detection.

Advances in Solid-Phase Extraction to Improve the Analysis of Per- and Poly-fluorinated Alkyl Substances

Environmental laboratories with high sample throughput often wish to analyze PCDD/Fs and PCBs in separate fractions. The cleanup method described here results in complete separation, and offers an alternative to fully manual or fully automated cleanup.

Microplastic pollution in the environment is a major concern for governments and companies worldwide attempting to understand and reduce the damage they cause. As well as the direct damage these plastic pellets can also act as chemical reservoirs that leach chemical contaminants into the environment and further damage ecosystems. The Column spoke to Manuel Miró from the University of the Balearic Islands, Spain, about his research into the pollution caused by chemical leaching from microplastics.

Understanding Microplastic Leaching

Environmental analysis of water presents many challenges, one of which is the potential presence of unknown contaminants. LCGC spoke to Imma Ferrer, an associate research scientist at the University of Colorado, USA, about some of her recent research on nontargeted analysis of water, including water from wastewater treatment plants, hydraulic fracturing wastewater, and environmental water samples.
