Abstract

Injector (40) for injecting a fluidic sample into a mobile phase in a sample separation apparatus (10), the injector (40) comprising a main flow path (100) between a fluid drive (20) and a sample separation device (30), wherein the fluid drive (20) is adapted to drive the mobile phase and the sample separation device (30) is adapted to separate the fluidic sample that is injected into the mobile phase, a discharge device (104) for discharging an, in particular predetermined, amount of the mobile phase from the main flow path (100), and a supply device (102) for supplying an, in particular predetermined, amount of the fluidic sample and/or of a solvent into the main flow path (100), wherein the discharged amount and the supplied amount compensate each other at least partially.
