Abstract:
1. A method for transferring fluid medium and materials with a minimum of band spreading and dispersion due to non-equal path-lengths between a first location and a second location, each possessing a different cross-sectional area, comprising: obtaining an apparatus, which said apparatus comprising a conduit of a predetermined shape having a first portal of predetermined size and a second portal of predetermined size, said conduit further having a path formed therein, said predetermined shape of said conduit being such that a length of said path through said conduit from said first portal to anywhere within said second portal is substantially the same, wherein said predetermined size of said first portal is smaller than said predetermined size of said second portal; performing one of the following steps connecting said second portal in said conduit to or with said second location, and aligning said second portal in said conduit to or with said second location; obtaining and introducing said fluid medium into said conduit via said first portal until said conduit is filled with said fluid medium; obtaining and introducing a sample material into said fluid medium via said first portal of said conduit; and obtaining and introducing additional fluid medium at a predetermined flow rate into said conduit via said first portal, wherein said fluid medium travels through said conduit and exits to said second location by way of said second portal of said conduit; wherein said sample material and said fluid medium are introduced into said first portal of said conduit, each traveling through said conduit and being distributed across said second portal following paths of substantially equal length through said conduit from said first portal to said second portal, thereby substantially eliminating end effects.
