AB - Most accelerator mass spectrometry measurements of <sup>26</sup>Al utilize the Al<sup>-</sup> ion despite lower source currents compared with AlO <sup>-</sup> since the stable isobar <sup>26</sup>Mg does not form elemental negative ions. A gas-filled magnet allows sufficient suppression of <sup>26</sup>Mg thus enabling the use of the more intense <sup>26</sup>AlO <sup>-</sup> ion. However, most AMS systems do not include a gas-filled magnet. We therefore explored the feasibility of suppressing <sup>26</sup>Mg by using a post-accelerator stripping foil. With this approach, combined with the use of alternative cathode matrices, we were able to suppress <sup>26</sup>Mg by a factor of 20. This suppression was insufficient to enable the use of <sup>26</sup>AlO<sup>-</sup>, however further refinement of our system may permit its use in the future. © 2012 Elsevier B.V.
