Scientists from the Chinese Academy of Inspection and Quarantine recently published a review on how green solvents can further the evolution of microextraction techniques.
Demystifying Sample Preparation for Headspace Analysis Using Direct Injection Mass Spectrometry
May 1st 2023Direct-injection mass spectrometry (DIMS) and gas chromatography (GC) approaches have some significant differences that are pertinent when analyzing volatile organic compounds (VOCs). We explain.
GC✕GC–TOF-MS Helps Quantify Pesticides in Water Susceptible to Contamination
April 28th 2023Pesticides in local surface and groundwaters were purified and enriched with solid-phase extraction, then analyzed using multidimensional gas chromatography coupled to mass spectrometry, with the results compared to those found by gas chromatography–quadrupole mass spectrometry.
New and Improved Method for Extracting α-Cellulose for Isotopic Analysis
April 26th 2023New 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.
Poisoned Chalice: Study Reveals Impact of Transformed Landscapes on Carnivores and Environment
April 10th 2023By 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.
Comparing the Chemical Profiles of Plant-Based and Traditional Meats Using GC–MS-Based Metabolomics
Untargeted GC–MS metabolomics with sample derivatization is shown here to be effective for measuring the chemical profiles of traditional and plant-based meat products.
