1. 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.
