How Does Mass Spectrometry Work?

Slide 3

February 2012

Mass spectrometry measures particles based on their mass-to-charge ratio. To do this, a sample (in the described method, the whole organism) is exposed to an ion source, and its particles (in the described method, proteins) ionized, separated based on their mass-to-charge ratio, detected and then the generated mass spectrum compared to a library of mass spectra.
