Mass measurements on radionuclides along the potassium isotope chain have been performed with the ISOLTRAP Penning trap mass spectrometer. For $^{35}\mathrm{K}$ (${T}_{1/2}=178$ ms) to $^{46}\mathrm{K}$ (${T}_{1/2}=105$ s) relative mass uncertainties of $2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$ and better have been achieved. The accurate mass determination of $^{35}\mathrm{K}$ ($\ensuremath{\delta}m=0.54$ keV) has been exploited to test …
