Abstract: The invention relates to a composition for dressing cutaneous lesions, in particular cutaneous leishmanial lesions or cutaneous lesions due to actinic keratosis, comprising, based on the total weight of the composition:—10.0 weight percent to 35 weight percent of a one or more diols, selected from the group comprising 1,2-propylene glycol, 1,2-pentanediol, 1,3-butanediol and 2,2?-[Ethane-1,2-diylbis(oxy)]di(ethan-1-ol),—2.0 weight percent to 20 weight percent of at least one first film-forming agent, selected from one or more of a cellulose derivative, hemicellulose, a hemicellulose derivative, chitosan, a chitosan derivative, or oligoglucosamines,—0.2 to 25.0 weight percent of at least one elastic second film-forming agent, selected from one or more thickening agents,—0.2 to 25.0 weight percent of one or more polymeric surfactants,—0.005 to 0.5 weight percent chlorate-free chlorite,—water adding up to 100.0 weight percent.

Abstract: In a column for high pressure liquid chromatography (HPLC) having a tube filled with sorbent for the passage of a solvent medium and samples to be analyzed, and a pressure jacket concentrically surrounding said tube, so that an annular interspace is provided which is filled with the solvent medium fed under pressure and in which the pressure can be equal or higher to the pressure within the internal tube, both ends of the interspace are sealed by means of packings surrounding the internal tube like stuffing boxes, and the ends of the internal tube are provided with perforated stoppers, which extend with a stud-like elongation into the internal tube to the region which is surrounded by the respective packing, so that the elongation support the wall of the internal tube against the sealing pressure of the packings. Accordingly, the internal tube can be a thin-walled glass column or even a hose of flexible plastics.

Abstract: In a column for high pressure liquid chromatography (HPLC) consisting of a glass column filled with sorbent concentrically surrounded by a pressure jacket leaving an interspace between the glass column and the pressure jacket, which interspace is sealed at both ends of the glass column and filled with the same medium as flows through the glass column, the pressure in the interspace being equal to the pressure at the inlet of the glass column, the improvement comprises packings surrounding the glass column like stuffing boxes and sealing the interspace between the glass column and the pressure jacket.
