Abstract
A sample management device which comprises a source flow path in which a fluidic sample can flow, a volume flow adjustment unit configured for adjusting a volume flow of the fluidic sample to be branched off from the source flow path at a fluidic coupling point, and a fluidic valve fluidically coupled with the source flow path and with the volume flow adjustment unit, wherein the fluidic valve is switchable into a branch off state in which the fluidic coupling point is established within the source flow path to branch off an adjustable volume of the fluidic sample from the source flow path via the fluidic coupling point while a flow of the fluidic sample in the source flow path continues.
Claims20
A sample management device, comprising:
- a source flow path in which a fluidic sample can flow;
- a volume flow adjustment unit configured to adjust a volume flow of an injectable fluid to be injected into the source flow path at a fluidic coupling point;
- and
- a fluidic valve fluidically coupled with the source flow path such that the fluidic valve forms a part of the source flow path, the fluidic valve being further fluidically coupled with the volume flow adjustment unit,
- wherein the fluidic valve is switchable into a coupled state in which the fluidic coupling point is established within the source flow path to inject an adjustable volume of the injectable fluid into the source flow path via the fluidic coupling point while the fluidic valve continues to form a part of the source flow path.
A method for managing a fluidic sample, the method comprising:
- providing a fluidic sample flowing in a source flow path;
- fluidically coupling a fluidic valve with the source flow path such that the fluidic valve forms a part of the source flow path, and further fluidically coupling the fluidic valve with a volume flow adjustment unit configured to adjust a volume flow of an injectable fluid to be injected into the source flow path at a fluidic coupling point;
- switching the fluidic valve into a coupled state in which the fluidic coupling point is established within the source flow path;
- and
- injecting a volume, being adjusted by the volume flow adjustment unit, of the injectable fluid into the source flow path via the fluidic coupling point while a flow of the fluidic sample in the source flow path continues and while the fluidic valve is in the coupled state and continues to form a part of the source flow path.
