Zusammenfassung:	<jats:p>A standard heavy ion nuclear structure facility has been used to detect several long-lived radioisotopes by counting the accelerated ions. The problem of eliminating strong isobaric background beams has been solved by combining the energy loss dispersion through a uniform A<jats:italic>l</jats:italic> foil stack with the high momentum resolution of an Enge split-pole magnetic spectrograph. Radioisotope concentrations in the following ranges have been measured: <jats:sup>14</jats:sup>C/<jats:sup>12</jats:sup>C = 10<jats:sup>–12</jats:sup> to 10<jats:sup>–13</jats:sup>, <jats:sup>26</jats:sup>A<jats:italic>l</jats:italic>/<jats:sup>27</jats:sup>A<jats:italic>l</jats:italic> = 10<jats:sup>–10</jats:sup> to 10<jats:sup>–12</jats:sup>, <jats:sup>32</jats:sup>Si/Si = 10<jats:sup>–8</jats:sup> to 10<jats:sup>–14</jats:sup>, <jats:sup>36</jats:sup>C<jats:italic>l</jats:italic>/C<jats:italic>l</jats:italic> = 10<jats:sup>–8</jats:sup> to 10<jats:sup>–11</jats:sup>.</jats:p>
