Le principe de l'ionisation électronique consiste à accélérer des électrons émis par un filament chauffé. Ceux-ci rentrent en collision avec les molécules. Si l'énergie cinétique fournie aux électrons est importante, quelques dizaines d’eV [électronvolts], alors un électron est arraché à la molécule au cours de la collision et un ion positif est formé. 1, record 1, French, - ionisation%20%C3%A9lectronique
