In the third part of Nicholas Snow's series on splitless GC injections, he discusses techniques for setting up the inlet and connections for optimized injections.
The “matrix effect” is one of the sticky details that can make the use of liquid chromatography (LC) for quantitative purposes challenging, even though it is conceptually quite straightforward. In this installment of LC Troubleshooting, Dwight Stoll reviews what is being referred to during talks about “matrix effects”, and discusses some of the potential origins of the phenomenon in practice.

Because PFAS is a hot topic, LCGC International will be releasing a video series about it, which will feature numerous North Carolina researchers. We preview this video series here.
A joint study conducted by the University of Modena and Reggio Emilia (Modena, Italy) and the University of Genoa (Genoa, Italy) aimed to optimize a liquid chromatography mass spectrometry (LC-MS) method using a zwitterionic phosphorylcholine hydrophilic interaction liquid chromatography (HILIC) column for detecting persistent and mobile organic contaminants (PMOCs) in wastewater. LCGC International spoke to researchers Caterina Durante (corresponding author of the piece) and Samuele Pellacani about their method and the results yielded.

The conference theme this year focused on collaboration, connection, and cultivation of the next generation of researchers.
Comprehensive information was derived through the utilization of a QuEChERS-UHPLC–MS/MS and GC–MS/MS method for the detection of 211 volatile and stable pesticide residues in 90 date fruit samples.
In this video interview from Pittcon, Elham "Elle" Akbari sat down with LCGC International to discuss her research, as well as the challenges of using liquid chromatography–mass spectrometry (LC–MS) and combustion ion chromatography (CIC) to characterize PFAS in environmental samples.
Researchers from Stanford University’s School of Medicine and Stanford Health Care report the development of a liquid chromatography high-resolution mass spectrometry (LC–HRMS) method for identifying hemoglobin (Hb) variants. The method can effectively separate several pairs of normal and variant Hb subunits with mass shifts of less than 1 Da and accurately identify them in intact-protein and top-down analyses.
At Pittcon 2025, Long Luo of the University of Utah sat down with LCGC International to discuss his laboratory's tetrahedron approach to their research.
Several sessions at Pittcon 2025 highlighted the importance of mentoring the next generation of analytical scientists in chromatography and spectroscopy. But what concrete actions can truly make a difference?
LCGC International sat down with Su to discuss what winning the Young Investigators in Separation Science Award means for him and his research. Su also passed along some advice for separation scientists and young professionals in this space.

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.
