A new study analyzed the trophic niches and niche overlap between native and introduced cyprinid fishes in Karacaören I reservoir using IRMS.

Exploring the impact of green chemistry on analytical chemistry and GC is the focus of this instalment of "GC Connections".

Everyone is talking about sustainability, and organizations are creating sustainability programs. But what does green chemistry really mean, and how does it apply to gas chromatography?

Researchers have shown the effectiveness of ion chromatography (IC) in identifying markers of forest fire emissions in rainfall samples, providing valuable insights into the signature of forest fire emissions and aiding in the development of models to predict and control air pollution resulting from these events.

A newly published review reveals insights into the history of capillary electrophoresis, from its development to its current state-of-the-art applications, through a comprehensive bibliometric analysis of publications between 1980 and 2021.

A new study has reported the preparation, characterization, and chromatographic evaluation of a nickel oxide deposited silica stationary phase in HILIC, which exhibited multiple retention mechanisms and enhanced chromatographic selectivity for analytes.

New article reviews the progress in suppression techniques for ion chromatography from 1981 to 2022, with an emphasis on the last ten years, and discusses the current challenges and future prospects regarding suppressors.

A new study has demonstrated a practical solution for the reliable compound-specific isotope analysis (CSIA) of trace-level pollutants in complex environmental samples, using 2DGC-IRMS.

New GC–MS research suggests that the presence of hemicellulose impurities in α-cellulose extracted from land plants may compromise reliable application of the 18O/16O ratio for environmental, physiological, and metabolic studies.

This year, the American Oil Chemists Society will convene in Denver, Colorado, for a conference filled with exciting talks about the latest developments related to edible oils, fats, surfactants, and related materials.

The Chromatography Forum of Delaware Valley Annual Symposium offers talks tomorrow on the analysis of environmental and industrial samples, including PFAS, agrochemical product impurities, and polycyclic aromatic hydrocarbons.

Direct-infusion tandem mass spectrometry (DI-MS/MS) enables researchers to quantify citrate isomers and isobars in biological samples with high accuracy and reliability.

A new semiquantification strategy efficient way to estimate suspect PFAS concentrations is described here.

In this LCGC blog, we reflect on the movement to make analytical chemistry more environmentally friendly, and how to potentially better those efforts for the industry's future.

By performing tissue analysis of caracals in captivity and in their natural African habitats, scientists were able to quantify uptake of toxic chemicals from the environment depending on how polluted they are.

The 20th International GC×GC Symposium will take place from 28 May–1 June 2023, and will be held in Canmore, Alberta.

A novel LC–MS/MS method, with a dual ESI and APCI source using simple solvent extraction for sample preparation, was validated for analysis of 102 pesticides and 5 mycotoxins regulated by Colorado state in dried hemp.
