FLUIDIC VALVE WITH SELECTIVLY SWITCHABLE STORAGE PATHS

摘要

A sample separation apparatus (100, 200) for separating a fluidic sample (104), the sample separation apparatus (100, 200) comprising: a first separation unit (102) for separating the fluidic sample (104); a first fluid drive (106) configured for generating a fluid flow for conducting the fluidic sample (104) to be separated through the first separation unit (102); a second separation unit (110), arranged downstream of the first separation unit (102), for further separating the fluidic sample (104) after treatment by the first separation unit (102); a second fluid drive (112) configured for generating a fluid flow for conducting the fluidic sample (104) or at least parts thereof, after treatment by the first separation unit (102), through the second separation unit (110); a fluidic valve (114) having a first inlet (116) fluidically coupled to one of the first fluid drive (106) and the second fluid drive (112); the fluidic valve (114) having a second inlet (118) fluidically coupled to the other of the first fluid drive (106) and the second fluid drive (112); the fluidic valve (114) comprising at least two different sets (131, 133) of storage paths, wherein each set of storage paths comprises a first storage path (128); and wherein the first storage path (128) of a first set (131) of said at least two sets of storage paths has a first volume and the first storage path (132) of a second set (133) of said at least two sets of storage paths has a second volume different from the first volume; the fluidic valve (114) being configured for selectively switching one set of said least two sets of storage paths to the first inlet (116) and the second inlet (118).

1. A sample separation apparatus for separating a fluidic sample, the sample separation apparatus comprising:
a first separation unit for separating the fluidic sample; a first fluid drive configured for generating a fluid flow for conducting the fluidic sample to be separated through the first separation unit; a second separation unit, arranged downstream of the first separation unit, for further separating the fluidic sample after treatment by the first separation unit; a second fluid drive configured for generating a fluid flow for conducting the fluidic sample or at least parts thereof, after treatment by the first separation unit, through the second separation unit; a fluidic valve having a first inlet fluidically coupled to one of the first fluid drive and the second fluid drive; the fluidic valve having a second inlet fluidically coupled to the other of the first fluid drive and the second fluid drive; the fluidic valve comprising at least two different sets of storage paths, wherein each set of storage paths comprises a first storage path; and wherein the first storage path of a first set of said at least two sets of storage paths has a first volume and the first storage path of a second set of said at least two sets of storage paths has a second volume different from the first volume; the fluidic valve being configured for selectively switching one set of said at least two sets of storage paths to the first inlet and the second inlet.
