The invention relates to a flow divider (20) and a process for dividing a fluid flow (30) into a number of fluid flows (31, 32), in particular in analytical and/or preparative fluid measurement technology and/or in micro-fluid systems. The flow divider (20) exhibits at least one working sensor (41, 42), which is assigned to one of the fluid flows (31, 32) and which comprises a control unit (55) for regulating the pressure of one of the fluid flows (31, 32) and/or for regulating one of the fluid flows (31, 32), which is coupled to the or each working sensor (41, 42) and an actuator (51) for changing this fluid flow (31). At least a number of working sensors (41, 42) corresponding to the number of divided fluid flows (31, 32) is provided, whereby respectively at least one of the working sensors (41, 42) is assigned to one of the fluid flows (31, 32) and whereby the working sensors (41, 42) enable recording of the respective fluid flow (31, 32). According to the process of the present invention the control unit (55) regulates the fluid flows (31, 32) such that the ratio between at least two of the fluid flows (31, 32) remains substantially constant.
