Mass spectroscopy is an analytical method for determining the mass-to-charge (m/z) ratios of ionized molecules or atoms to infer their molecular mass, composition, and structural features. In typical workflows, samples are ionized (e.g., by electron ionization, electrospray ionization, or MALDI), separated according to m/z in a mass analyzer (such as quadrupole, time-of-flight, ion trap, or Orbitrap), and detected to generate a mass spectrum. The method enables high-sensitivity, high-specificity characterization of complex mixtures, supports quantitative analyses through calibrated signal intensities, and is widely integrated with separation techniques (e.g., liquid or gas chromatography) to enhance resolution and analyte identification.
Atmospheric methane levels have surged to record highs in recent years and are projected to increase by as much as 13% by 2030, according to a report from the Climate & Clean Air Coalition. As scientists work to better understand ...
