Claim:
1. A method for feeding a sample into an analysis branch of a liquid chromatography system, the method comprising: supplying a solvent or a solvent mixture from at least one solvent branch at a volume flow {dot over (A)} into the analysis branch, the at least one solvent branch is an input into a unidirectional valve, the analysis branch is an output out of the unidirectional valve; feeding at least one sample from at least one sample branch at a volume flow Ė into the analysis branch within a predetermined time interval, the at least one sample branch is another input into the unidirectional valve reducing the volume flow {dot over (A)} during the predetermined time interval, in which the reducing of the volume flow {dot over (A)} causes an increase in the volume flow Ė, and a control device controls the volume flow {dot over (A)} and the volume flow Ė; outputting a substantially constant volume flow Ċ in the analysis branch resulting from a sum of the volume flows {dot over (A)} and Ė.
