Abstract
The invention concerns a method for separating fractions of a mixture using a chromatography device. The method includes the following steps: controlling in one node of the device, the history of a specific variable of the fractions of the mixture to be separated; detecting one characteristic point of the history, the characteristic point being between two successive steps of fraction collecting; comparing the position of the characteristic point relative to a target position; adjusting the amount of mobile phase modifying the position of the characteristic point to cause the position of the characteristic point to coincide with the target position. The invention also concerns a device for implementing the method. The method enables the operation of the device to be automatically set.
