Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

Beijing Zhongke Journal Publising Co. Ltd. The traditional method for detecting dissolved gases in the deep sea is offline detection, which combines pressure sampling with laboratory analysis. This ...

The Peregrine Ion Trap Mass Spectrometer (PITMS) has returned to Earth after an eventful ten days in space, burning up on re-entry over the Pacific Ocean. Developed at short notice by RAL Space, the ...

Day 1 of the annual meeting of the American Society for Mass Spectrometry (ASMS; NM, USA) has been jam-packed with press conferences from the biggest names in mass spectrometry, and I have been to ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Just how far mass spectrometry—the use of tools measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample—has progressed over the past century can be seen in a new exhibit ...

Purdue researchers developed a mass spectrometry system that accelerates chemical reactions without heat or catalysts, ...
