m/z 
Unit In mass spectrometry, where m=mass of Ion, z=charge. number of Ions. In mass analysis, an 
electron Is taken from molecules to create single charged Ions. If two electrons are removed, 
double charged Ions are produced. The number of electrons removed Is the charge number (for 
positive Ions), m/z represents mass divided by charge number and the horizontal axis In a mass 
spectrum Is expressed In units of m/z. Since z Is almost always 1 with GCMS, the m/z value Is often 
considered to be the mass.
