    摘要: A process for characterizing a sample comprising a population of linear macromolecules of interest (104) and a population of long chain branched macromolecules of interest (103), the process including four steps. The first step is to provide a flow through separating medium (100) and a liquid eluant (101) in which the macromolecules of interest dissolve, the separating medium defining flow through channels (102), the eluant flow rate and the average diameter of the channels being in a range so that the linear macromolecules of interest elute before the long chain branched macromolecules of interest (105) (106). The second step is to introduce a sample into the liquid eluant. The third step is to flow the liquid eluant under pressure through the channels (102) of the separating medium (100). The fourth step is to differentiate the linear macromolecules of interest (104) from the long chain branched macromolecules of interest (103) based on their successive elution volumes established in the third step such as by determining the refractive index of the successive elution volumes or by subjecting the successive elution volumes to size exclusion chromatography.

    摘要: A method for analysing a mixture M comprising (i) a first monodisperse species, and (ii) a second species having a response coefficient which is distinct from the response coefficient of the first species (i) on at least one detection device, said method comprising the following steps: (A) the mixture M is injected at the inlet of a capillary tube and forced to be transported in said tube by the flow of a carrier liquid induced by a positive hydrodynamic and/or hydrostatic pressure between the inlet and the outlet of the capillary, whereby a phenomenon of Taylor dispersion of the species of the mixture M occurs in the tube; (B) by using a detection device able to detect simultaneously both species (i) and (ii) and placed in the region of the outlet of the capillary tube, a signal reflecting the Taylor dispersion obtained in step (A) is measured; (C) the signal obtained in step (B) is analysed, so as to determine specific contributions of species (i) and (ii) and thereby establishing at least one of the followings: —the content of species (i) and/or (ii) in the mixture M; and/or, —the mean hydrodynamic radius of the species (ii) or the hydrodynamic radius of species (i).

    摘要: A method is disclosed for determining the distribution according to size of particles which make up a noncontinuous phase dispersed within a matrix which is not completely soluble in an aqueous solution. The method involves dissolving the matrix containing the particles in an essentially nonaqueous liquid causing the particles to be suspended. The suspension is then eluted through a separating medium which sorts the particles according to size. A detector monitors the effluent from the separating medium and creates a record of the data. This record is then compared to data obtained from known standards in order to estimate the size distribution in the sample.
