Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass ...

IT has been generally assumed that the explanation of the diffuse absorption spectra of aldehydes and ketones in the ultra-violet is the occurrence of a process of predissociation involving the ...

The American Society for Mass Spectrometry has announced its award winners for 2025, including Jack Henion of Cornell University and Vilmos Kertesz of Oak Ridge National Laboratory. The instrument ...

Oak Ridge National Laboratory (ORNL) has taken a significant leap with the introduction of next-gen mass spectrometry equipment that is revolutionizing the study of complex microbial systems ...

The research in the Biomolecular Mass Spectrometry and Proteomics groups focuses on the use of mass spectrometry to understand the inner workings of cells. Mass spectrometry enables the ...

We introduce a novel high-precision method for oxygen-isotope analysis of iron (oxyhydr)oxides using high-temperature conversion isotope ratio mass spectrometry (HTC-IRMS). In this approach, a finely ...

With personal care products becoming increasingly popular, acetone sales are on the rise. The industry expects the size of the acetone industry to reach USD 6,955.1 million by 2023 and USD 13,521.8 ...

The Adani group has transferred all the spectrum it had purchased in a 2022 auction to Bharti Airtel, effectively signalling a pause in its ambitious telecom play. This comes after the ports-to-energy ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

For the first time, we take light-travel time effects on the spectrum formation into account, which affect the shapes and strengths of the observable emission lines, as well as the inferred SN ...

Every analyst using GC-MS should have a fundamental understanding of how a mass spectrum is generated and if a library match is correct or not. This course takes this a step further to enhance mass ...

Exposed ductwork hangs overhead. Why the downgrade? Harvey’s parish was forced to relocate its traditional Latin Mass, an ancient version of the Catholic liturgy that has set off one of the ...
