Publication number: 20240077460Abstract: An injector, for injecting a fluidic sample into a flow path between a fluid drive and a sample separation unit, includes a sample accommodation volume, a sample drive, and a fluidic valve switchable to selectively couple the volume with the flow path or decouple the volume from the flow path. In an injection switching state, the fluid drive, the separation unit and the sample drive are coupled by the valve so that fluid driven by the sample drive and flowing from the volume to the separation unit and further fluid driven by the fluid drive and flowing from the fluid drive to the separation unit are combined at a fluidic connection upstream of the separation unit. A control unit controls a pressure of the fluid and/or the further fluid during injecting.Type: ApplicationFiled: September 18, 2023Publication date: March 7, 2024Inventors: Daniel Thielsch, Thomas Ortmann, Sam Wouters
