You're invited to publicize your 2024–2025 new product introductions in LCGC. Here's how to get your products included.
GC×GC–MS With Flame Ionization Aids AI Strategies for Raw Hazelnut Volatilome Evaluation
July 11th 2023Quality control of raw hazelnuts is already a highly specific process, but has limitations including operator influence, duration, and lack of standardization. AI is now assisting in quality decision-making using GC×GC analysis.
Human Body Odors Tested for Mosquito Attraction in Zambia
July 10th 2023Stephanie Rankin-Turner and colleagues at Johns Hopkins Bloomberg School of Public Health have recently performed research in Zambia indicating that mosquitoes are more attracted to humans who exhibit abundant levels of certain volatile carboxylic acids.
Two-Color Femtosecond Laser Ion Mass Spectrometry Used for Analysis of Carcinogenic Compounds
July 6th 2023Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are suspected to be carcinogenic, and improvements are sought to improve gas chromatography–mass spectrometry (GC–MS) methods traditionally used for this analysis.
Study Reveals Low Transfer of Pesticide Residues from Herbs to Infusions
June 30th 2023A recent study reveals that pesticide residues in herbs have a low transfer rate to herbal infusions, ensuring safer consumption of these products. The validated analytical method used in the study provides valuable insights into the levels of pesticide residues in herbs and their limited presence in the resulting infusions.
Revolutionizing Atmospheric Monitoring: Hourly Tracking of Krypton-85 with Online Analysis
June 12th 2023A temperature-controlled cryogenic distillation and gas chromatography, atom trap measurement system is used for precise analysis of atmospheric 85Kr abundance. This advanced technology enables online monitoring with high sensitivity and reduced sample size requirements.
Exploring Mosquito Olfactory Preferences with Whole Body Volatilomics
June 7th 2023In a talk at ASMS 2023, Stephanie Rankin-Turner of the Johns Hopkins Bloomberg School of Public Health detailed how thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) analyzed the body odor of humans to quantify mosquitos' attraction to them.
An Interview with AI About Its Potential Role in Separation Science
May 17th 2023We interviewed an AI program (ChatGPT) for LCGC North America asking questions about AI and its role in various applications for separation science to include data analysis, and high performance liquid chromatography (HPLC), hydrophilic-interaction chromatography (HILIC), reversed-phase liquid chromatography (RPLC), liquid chromatography–mass spectrometry (LC–MS), gas chromatography–mass spectrometry (GC–MS), high resolution mass spectrometry (HRIM–MS), high resolution tandem mass spectrometry (HRMS/MS), and related topics.
New Device Developed to Detect Pollutants in Vehicle Emissions
May 15th 2023A new methodology for trapping polycyclic aromatic hydrocarbons from vehicular emissions using an in-tube extraction device (IT-FEx) and analyzing them through gas chromatography-barrier ionization discharge detection (GC-BID) has been developed and tested successfully, according to a study published in the Journal of Chromatography A.
Rising Stars of Separation Science: Juan L. Benedé
May 9th 2023This month we interview Juan L. Benedé from the University of Valencia in Spain, about his work developing microextraction approaches, based on the use of sorbent materials, for application to complex matrices, and his focus on the determination of disease biomarkers in biofluids.
