We are considering purchasing a used Agilent 5975 and have seen various mentions that a different magnet is needed for the source when running on hydrogen.On our existing Perkin Elmer Turbomass there is no such option or need. I'm aware that there can be catalysed reduction of certain groups (amines, nitro etc) with H2 and that Agilent offer a different lens with larger aperture to help but we've been running with H2 for years with the PE.

Has anyone tried this on a 5975 without such an 'upgrade' and what does this actually do ?
