ABSTRACT:
A method and an arrangement by which separating liquid streams, such as occur for example in cell sorters, are monitored automatically. An image of the separating liquid streams is recorded and the position of a separation point at which the drops separate from a column of liquid is found using image analysis methods. Various solution possibilities are indicated for the suitable preparation of the image information for easier processing.
