Electron-capture Mass Spectrometry

Electron-capture mass spectrometry (EC-MS) is a type of mass spectrometry that uses electron capture ionization (ECI) to form negative ions from chemical compounds with positive electron affinities. The approach is particularly effective for electrophiles. In contrast to electron ionization, EC-MS uses low energy electrons in a gas discharge. The technique can be used with gas chromatography-mass spectrometry.

Famous quotes containing the word mass:

    What will happen once the authentic mass man takes over, we do not know yet, although it may be a fair guess that he will have more in common with the meticulous, calculated correctness of Himmler than with the hysterical fanaticism of Hitler, will more resemble the stubborn dullness of Molotov than the sensual vindictive cruelty of Stalin.
    Hannah Arendt (1906–1975)
