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.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
