The Mead Group at UNC Wilmington studies the occurrence and transport PFAS in wet and dry depositions, tracing their sources to inform regulators. In the first part of our interview, we spoke with Mead and several members of his team about the work they do for the North Carolina PFAS Testing Network and learn more about the network.

In this final part of our interview with Ezgi Gürler of Females in Mass Spectrometry, we ask about her upcoming research that will occur during her tenure at DESY-CSSB and Uppsala University.

Researchers attempted to ascertain the relationship between vitamin D levels in athletes and the structural and functional values of their hearts assessed through electrocardiographic and echocardiographic parameters. Vitamin D levels were measured using high performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS).

In this second part of our interview with Ezgi Gürler of Females in Mass Spectrometry, we ask about her time at BIOCEV developing advanced fragmentation schemes for non-covalent complexes and Norovirus P-dimer proteins.

In this first roundtable discussion focused on Women in Chromatography, LCGC International spoke with Diane Turner, Jacqueline Hamilton, and Caroline Gauchotte-Lindsay, who discussed emerging trends in chromatography and useful resources for women in chromatography.

Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).

Researchers from KU Leuven explored two-dimensional liquid chromatography (2D-LC)’s application to profile micropollutants in wastewater.

The experts conclude the panel by addressing additional regulatory challenges and exploring how the industry can collaborate to tackle these issues moving forward.
