Quantum mechanics dictates how particles and forces interact, and thus how atoms and molecules work, for example, what happens when a molecule goes from a higher-energy state to a lower-energy one. But beyond the simplest molecules, the details become very complex. Now, a Pixel-Imaging Mass Spectrometry camera and a femtosecond vacuum ultraviolet light source are showing how does quantum mechanics work in larger, more complex systems.
Salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms, the effluent from which can pollute rivers, lakes and oceans. German and Chilean scientists have used fluorescence measurements, high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy to answer this question.
Drugs containing gold have been used for centuries to treat conditions like rheumatoid arthritis. In addition, they can be effective against cancer and HIV. One mechanism by which they work could occur because gold ions force the zinc ions out of zinc fingers—looped, nucleic acid binding protein domains. American researchers have characterised such “gold fingers” using ion mobility mass spectrometry and identified the exact gold binding sites.
Analytik Jena and Bruker Daltonics develop a new ultra-high throughput screening product for biopharmaceutical labs.
Sciex has announced the latest introduction to its X-Series quadrupole time-of-flight platform
Ionicon Analytik introduces its new compact, high-resolution VOC analyser, the PTR-TOF 4000
Shimadzu has released its new LCMS-8045 triple quadrupole mass spectrometer
By measuring the height profile of the sample prior to analysis, mass spectrometry imaging can now visualise the distribution of chemical substances on samples with non-flat surfaces.
SIFT-MS has shown promising results for the detection of cancers of the oesophagus and stomach in a large patient trial presented at the European Cancer Congress 2017.
