Abstract: The invention relates to a method for carrier-free deflection electrophoresis, in which a separating agent used as carrier and a sample to be examined flow through a separating chamber (1) from an admission end to an outlet end, and the sample is physically separated into fractions, which are to be collected, by an electrode-generated electric field. The method is characterized in that the entry of the sample into a separating chamber between the electrodes occurs in the absence of voltage in the electrodes; in that voltage is applied to the electrodes after the sample has entered the separation area; and in that the electrophoretic separation is conducted only as long as the whole sample is essentially located in the separating area between the electrodes.

Abstract: A communication network has a plurality of mutually connected network nodes in which in each case network data relating to the network topology of the entire communication network are maintained. Depending on the network data, routing tables for connection paths to all remaining network nodes are created. If an event that influences the network topology of the communication network occurs, on the one hand the network data maintained therein are updated by the network node detecting the event. On the other hand, a broadest message corresponding to the event is transmitted to the other network nodes, following the reception of which the respective network nodes update the network data maintained therein.

Abstract: In carrier-free continuous deflection electrophoresis problems are encountered in the collection of fractions and it is necessary to use hose pumps with a number of channels corresponding to the number of fractions desired. This arrangement is not only elaborate and susceptible to disturbance, for a great variety of reasons, but even more importantly it necessitates a certain minimal flow velocity within the separation chamber. To improve the effectiveness of separation it is proposed by the present invention to adjust the outflow rate from the separation chamber in the region of its outlet end by introducing an additive medium with a predetermined flow rate in countercurrent to the flow direction of the separation and sample media. In this way the time the sample spends in the electric field and hence the corresponding separation effect is considerably increased.
