Each year, LCGC International presents two awards at Pittcon to the winner of the Lifetime Achievement in Chromatography Award and the Emerging Leader in Chromatography Award. This year, Christopher Pohl is the recipient of the Lifetime Achievement Award and Katelynn Perrault Uptmor is the recipient of the Emerging Leader award. The award presentation, which will honor Pohl and Perrault Uptmor, will take place on Tuesday March 4th from 8:30–11:40 am.

In this third part of our interview with Christopher Pohl, he tells us about his most treasured accomplishments from throughout his storied career.

Here, you’ll find an overview of some of the networking opportunities throughout the week that are available for attendees.

In this second part of our interview with Christopher Pohl, we learn about the mentors Pohl turned to throughout his career, and the important teachings he took from them.

Gas chromatography-mass spectrometry (GC-MS), electronic tongue (E-tongue), electronic nose (E-nose), and sensory analysis were used to investigate the flavor profiles of beef jerky from four specific regions of China: Xinjiang, Tibet, Sichuan, and Inner Mongolia.

Researchers investigated the protective effects of enzymatically digested velvet antler (VA) extract on the mitochondria in astrocytes, which are essential organelles regulating oxidative stress. Proteomic and metabolomic results using liquid chromatography-mass spectrometry (LC-MS/MS) identified enriched bioactive ingredients which display significant protective effects against mitochondrial stressors in astrocytes compared with other health functional ingredients.

In this video interview, Emanuela Gionfriddo, Daniel Armstrong, and Nicholas Snow preview their talks at Pittcon, as well as give their opinions about what topics they hope to explore more at the conference.

In this first part of our interview with Christopher Pohl, he discusses the 2025 LCGC Lifetime Achievement Award, and what this means to him.

The biodegradability of poly(butylene succinate) (PBSu) in marine environments is under scrutiny. As it is well known that the biodegradability of biodegradable polymers depends on their molecular weight, researchers explored the effect of that factor of PBSu on its biodegradability through biochemical oxygen demand (BOD) testing in seawater, with samples of differing molecular weight prepared with size-exclusion chromatography (SEC).

Exploring the alterations in metabolites of wet age-related macular degeneration (wAMD), metabolomic analysis was performed on the aqueous humor of 30 patients with wAMD receiving anti-vascular endothelial growth factor (anti-VEGF) treatments and 20 controls, via ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).

The Harvey W. Wiley Award is presented every year to a scientist, or group of scientists, who have made outstanding contributions to analytical method development in areas of interest to AOAC INTERNATIONAL.

In this Q&A interview, Samiksha Singh discusses her team’s latest research in microplastics research, which provided insight into how marine monitoring can improve mitigation of plastic pollution.

Researchers at Jilin University (Changchun, China) developed a highly sensitive, rapid, and accurate method for analyzing neurotransmitters (NTs) in rat spinal cord tissue. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UHPLC-QqQ-MS/MS) in conjunction with ultra-ionic liquid dispersive liquid-liquid microextraction (UA-MIL-DLLME) were used to extract NTs for analysis.

A joint study between the Institute for Environment and Energy, Technology and Analytics (IUTA e. V., Duisburg, Germany) and Heinrich Heine University Düsseldorf (Germany) explored the combination of size exclusion chromatography (SEC) with diode array detector (DAD) and capillary-enhanced Raman spectroscopy (CERS) to directly analyze hemolyzed serum samples. We spoke to Jana Thissen, first author of the paper resulting from this study, about her team’s work.

High-speed counter current chromatography (HSCCC), an advanced liquid-liquid chromatography technique employing both a liquid stationary phase and a liquid mobile phase (effectively eliminating irreversible adsorption), was used to harvest allicin from garlic.

A pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) methodology has been specifically developed for the identification and quantification of seven polymers commonly found in tap water. The researchers responsible for the approach state that it prioritizes both time and cost efficiency without compromising the thoroughness of marker spectrum detection and confirmation.

Christopher A. Pohl and Katelynn A. Perrault Uptmor are the winners of the 18th annual LCGC Lifetime Achievement and Emerging Leader in Chromatography Awards, respectively. The LCGC Awards honor the work of talented separation scientists at different stages in their career (See Table I, accessible through the QR code at the end of the article). The award winners will be honored during an oral symposium at the Pittcon 2025 conference held March 1-5, in Boston, Massachusetts.

In Part II of our exploration of splitless injection, we will see that it is a surprisingly complex process, and that it is difficult to understand because we cannot see what is happening during the injection process. For this discussion, we will think of the injection process as beginning with the syringe plunger being depressed and ending with the start of a temperature program in the column oven. In most splitless injections, this process requires 30 s to 1 min. There are several band broadening and focusing mechanisms that affect the peak shapes, widths, and heights resulting from splitless injection.

This article delves into advancements in green chromatography, focusing on how innovative HPLC column design can drive eco-conscious practices.

In this installment, I primarily discuss considerations to keep in mind when choosing buffering additives that will be used for LC methods involving UV absorbance detection.

LCGC International is celebrating the National Day of Women and Girls in Science by highlighting the work of women in analytical chemistry.
