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