Analyzing the Impact of a Music Festival on Local Environment
Spring Scream is one of the largest music festivals held in Taiwan, and is reported to be associated with drug abuse and addiction.
Spring Scream is one of the largest music festivals held in Taiwan, and is reported to be associated with drug abuse and addiction. A new study to be published in the journal Environmental Science & Technology presents the investigation of 30 targeted emerging contaminants (ECs) in the local environment using solid-phase extraction and liquid chromatography coupled to tandem mass spectrometry (SPE–LC–MS–MS).1 Samples of wastewater influent and effluent were collected before, during, and after the festival. The authors found that seasonal variations were observed with higher concentrations of ECs in April during the festival.- B.D.

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.
