The conserved‐vector‐current (CVC) hypothesis of the weak interaction and the unitarity of the Cabibbo‐Kobayashi‐Maskawa (CKM) matrix are two fundamental postulates of the Standard Model. While existing data on CVC supports vector current conservation, the unitarity test of the CKM matrix currently fails by more than two standard deviations. High‐precision mass measurements performed with the ISOLTRAP experiment at ISOLDE/CERN provide crucial input for these fundamental studies by greatly improving our knowledge of the decay energy of super‐allowed β decays. Recent results of mass measurements on the β emitters 18Ne, 22 Mg, 34Ar, and 74Rb as pertaining to weak‐interaction studies are presented.
