Negative ion chemical ionization (Cl − ) mass spectra of the commonly occurring amino acids are simple and give information regarding molecular weight by the presence of [M + Cl] − adduct in the case of simple amino acids and [M − H] − in the case of amino acids containing additional polar groups. tert ‐Butyloxycarbonyl (BOC)‐protected di‐, tri‐ and tetrapeptides also given abundant [M + Cl] − ions.
