According to Schenk, the widespread popularity of the hydraulic fracturing technique coupled with horizontal drilling has introduced a new set of needs for analytical testing. Proppants and friction reducers are used in the process of hydraulic fracturing to improve productivity, but their behavior in downhole conditions have not been fully characterized. Leaching from resin-coatings of the proppants and byproducts formed under high-temperature and pressure can be of concern to productivity and groundwater contamination. In these experiments, gas chromatography–mass spectrometry (GC–MS), GC–vacuum ultraviolet spectroscopy (VUV), and liquid chromatography (LC) were all examined to identify and quantify compounds from various resin-coated proppants and friction reducers used in the fracking procedure.
Determining Enhanced Sensitivity to Odors due to Anxiety-Associated Chemosignals with GC
May 8th 2025Based on their hypothesis that smelling anxiety chemosignals can, like visual anxiety induction, lead to an increase in odor sensitivity, a joint study between the University of Erlangen-Nuremberg (Erlangen, Germany) and the Fraunhofer Institute for Process Engineering and Packaging (Freising, Germany) combined behavioral experiments, odor profile analysis by a trained panel, and instrumental analysis of odorants (gas chromatography-olfactometry) and volatiles (gas chromatography-mass spectrometry).
Investigating 3D-Printable Stationary Phases in Liquid Chromatography
May 7th 20253D printing technology has potential in chromatography, but a major challenge is developing materials with both high porosity and robust mechanical properties. Recently, scientists compared the separation performances of eight different 3D printable stationary phases.
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
