Abstract

A process and device for metering different solutions is provided with which a high rate of repetition of drugs to be metered is possible. To accomplish the object, provisions are made for taking fluid volumes in the range of 50 nL to 50 μL from a fluid source (2, 3, 4, 5) in rapid succession in time according to the time multiplex method and for introducing them into a collecting channel (10) without mixing.
