A recent study expanded PFAS biomonitoring in hair to 26 analytes—including fluorotelomer sulfonic and carboxylic acids, FTUCAs, diPAPs, diSAmPAP, FOSA, N-EtFOSAA, and the ionic liquid NTf2—to characterize exposure patterns in non-occupationally exposed individuals and explore links with physical and lifestyle factors. LCGC International spoke to Miriam Haußecker, lead author of the paper that resulted from this study.

This week, LCGC International published a variety of articles on hot topics in separation science. From an interview about the evolution of ion chromatography to an article about the top ten topics that new liquid chromatography (LC) users should know, we’ve highlighted some of the most popular articles that were published this week.

Achieving lasting gender equity in chromatography demands systemic reform, from rethinking promotion criteria and tackling bias in publishing to creating flexible career pathways that retain talent. With the active support of allies and institutions, these changes can build a stronger, fairer, and more innovative scientific community.

The aim of this article is to provide a validated and optimized CIC-based method for accurate measurement of total fluorine in materials with polymeric PFAS content in the low-ppm range, which could be used in the consumer electronics and potentially other industries. This, in turn, can aid companies in tracking and mitigating PFAS ahead of regulations.

Joachim Weiss is a pioneer in the true meaning of the word in the world of ion chromatography (IC). In this in-depth interview, Joachim offers his insights into the past, present, and future of the technique.

Researchers from the University of Toledo and Wayne State University investigated the prognostic importance of oxylipins in a cohort of 90 participants with heart failure with preserved ejection fraction (HFpEF) with preserved ejection fraction over a 5-year period used high-performance liquid chromatography (HPLC) to extract polyunsaturated fatty acyl (PUFA) metabolites from serum samples.

Artificial intelligence and machine learning have the potential to reshape the scientific landscape. Yet, as the International Women in Chromatography founders stress, these advances must be grounded in uncompromising data quality and rigorous quality control to ensure reliable, transformative science.

HPLC is indispensable in pharmaceutical analysis and quality control despite some notable shortcomings in laboratory testing and processes to ensure regulatory compliance.

Liquid chromatography (LC) is an incredibly powerful analytical tool that can be used to characterize materials across an astonishingly wide array of applications, ranging from 1 megaDalton polystyrenes to small genotoxic impurities of concern in pharmaceutical manufacturing. However, with this power also comes with a lot of detail related to successful operation of an LC instrument and analysis of the data it produces. This can be challenging when onboarding new LC users—how do we train someone new, where do we start, and which resources are best? In this installment, I will highlight ten high priority topics that every new user should be familiar with, no matter the training mechanism.

Research conducted by the University of Tolima evaluated the effects of chromium-yeast supplementation at different doses and timepoints on physiological and molecular stress biomarkers in heat-stressed lambs, with chromium bioavailability assessed by blood levels using absorption chromatography.

Chris Pohl, a recognized and respected contributor to the evolution of ion chromatography and recipient of LGCC International’s Lifetime Achievement Award, discusses the past, present, and future of ion chromatography (IC).

Researchers characterized lipid profiles from Hass Portuguese avocado pulp using C18 reversed-phase HPLC-MS/MS, and their biological activities were evaluated.

The founders of the International Women in Chromatography group share their diverse career paths, the challenges of balancing motherhood with scientific work, and the systemic barriers women face in advancing within the field.

In the first in a series of interviews to celebrate the 50-year anniversary of ion chromatography (IC), Joachim Weiss, Chris Pohl, and Brett Paul offer advice to chromatographers who want to specialize in this branch of separation science.

A recent joint study by the University of Lyon (Villeurbanne, France) and the University of Texas at Arlington studied the chromatographic variations induced by replacing classical solvents with carbonate esters using simple reverse phase liquid chromatography (RPLC), hydrophilic interaction chromatography (HILIC), and normal phase liquid chromatography (NPLC) separations of model compounds. LCGC International spoke to Sakil Islam, one of the authors of the resulting paper.

The International Women in Chromatography group was founded to combat gender disparity in the field, creating a supportive global community that fosters belonging, advocacy, and recognition for women at all career stages. LCGC International spoke with the founders to find out more about the initiative.
