Abstract:

A process for characterizing a sample comprising a population of linear macromolecules of interest () and a population of long chain branched macromolecules of interest (), the process including four steps. The first step is to provide a flow through separating medium () and a liquid eluant () in which the macromolecules of interest dissolve, the separating medium defining flow through channels (), 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 () (). 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 () of the separating medium (). The fourth step is to differentiate the linear macromolecules of interest () from the long chain branched macromolecules of interest () 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.

Abstract:

An intuitive user interface is provided for endoscopic view visualization. The user interface may permit individual or simultaneous navigation through images displayed in an endoscopic view window, a three dimensional overview window, and a multi-planar reformatted window. An operation performed directly on one of the windows may commence the navigation. The endoscopic view window may be divided into a plurality of sub-regions, each sub-region having a corresponding navigation function. The endoscopic view window and the three dimensional overview window may have corresponding icons related to a single location in corresponding images being displayed. The corresponding icons may be color coded to facilitate intuitive alignment of the corresponding images displayed in the different windows. The three dimensional overview window may have a geometric icon to facilitate intuitive alignment of the corresponding images. The multi-planar reformatted window may permit spherical navigation through the images displayed.
