The process is based on a program that switches the bypass grove of the injection valve into the flow line for cleaning. This switching event is performed at the end of the equilibration time to ensure that the bypass grove is filled with the start concentration of the mobile phase. Otherwise the separation could be influenced, especially if microbore columns are used.
