1,194,376. Chromatography. V. PRETORIUS and. H. H. HAHN. 25 July, 1967 [2 Aug., 1966], No. 34180/67. Heading B1X. In a liquid chromatographic separating process, retention of solute ions, amendable to reversable electrodeposition is induced by applying an alternating current potential difference having a puke-shape of diminishing width at increasing potential levels 'between a reference locality and a locality on the retarding phase. The pulse shapes may be as in Fig. 4, may be imposed on a direct current potential, and may be applied between either end of the retarding phase, or (as in Fig. 1, not shown) between electrically pervious packing 24, Fig. 5 and electrode material 25 which forms the reference locality. Specifications 1,169,523 and 1,120,364 are referred to.
