Eluent conditions:
(1) Water, acetonitrile and ethanol, either singly or in mixtures of any ratio, may be used as eluent. With aqueous ethanol solution the flow rate should he lower than normal, because of their relatively high viscosity.
(2) Various types of buffers soluble in acetonitrile or ethanol (such as tetrapropylammonium acetate or sodium acetate) may be used together with the above components, so long as no observable precipitation ocurs in the eluent.
