<p>A substantially urea-free composition, consisting of (a) 10 to 30 % by weight of a substantially non-crosslinked water-soluble polymer having an average molecular weight of less than 100 000, (b) up to 50 % by weight of at least one organic solvent which is miscible with water, and (c) at least 20 % by weight of an aqueous buffer solution, the composition having a viscosity of 50 to 600 mPa.s. The composition can be used as stationary phase in the capillaries of capillary eletrophoretic devices for separating mixtures of electrically charged organic compounds, in particular of low molecular oligonucleotides.</p> |
