A technique for the simplification of fast‐atom bombardment (FAB) spectra of polysulfonic acids, especially azo dyes complicated by sodium, is discussed. The sodium may be present as the sulfonate salt or the salt may be formed during FAB analysis from impurities present in the sample. The incorporated sodium as well as other impurities which may be present in commercial samples are removed by means of a simple cationic‐exchange‐resin procedure, yielding simplified and unambiguous FAB spectra of the sodium‐free material.
