The Delta Ray Road Trip
Attributing the source of CO2 presents challenges for environmental agencies and research institutions. CO2 isotope ratios carry information about the emitter. However, their continuous monitoring presents a complex task. The Thermo Scientific Delta Ray CO2 Isotope Ratio Infrared Spectrometer (IRIS) enables scientists to perform isotope ratio analysis directly where the sample is taken. On a road trip through Canada, the analyzer was installed in an RV and continuously monitored the CO2 concentrations, 13C and 18O isotope ratios coast to coast.
Improving Fluorescence and Raman Techniques for Environmental Microplastic Analysis
March 31st 2025A recent study conducted at the LaserLaB Amsterdam and Vrije Universiteit Amsterdam (the Netherlands) explored spectroscopic imaging techniques, including Raman and fluorescence microscopy, for characterizing microplastics (MPs), focusing on optimizing sample preparation, particularly density separation, and Nile Red staining.Spectroscopy spoke to Merel Konings, corresponding author of the paper resulting from the study, about her work
New Study Provides Insights into Chiral Smectic Phases
March 31st 2025Researchers from the Institute of Nuclear Physics Polish Academy of Sciences have unveiled new insights into the molecular arrangement of the 7HH6 compound’s smectic phases using X-ray diffraction (XRD) and infrared (IR) spectroscopy.
