Abstract: PROBLEM TO BE SOLVED: To provide a device and a method capable of economically and highly reproducibly separating the amount of liquid in a range of nanoliter to picoliter. SOLUTION: A computer 4 loading a computer program for synchronizing a fine injection device 1 and a pump 2 is configured based on the program to control and synchronize a function for allocating the sample amount by the fine injecting device 1 and a function for tracking the part (12, 12', 12") of the pump 2 depending on the sample amount actively allocated by the fine injection device 1.

Abstract: A computer for synchronizing a system consisting of a micro-ejection unit (1) and a pump (2) connected by a liquid line (3) actively defines a sample volume and releases the defined sample volume, and tracks a part of the pump carrying the liquid by a value depending on the sample volume released by the micro-ejection unit to avoid high pressure differences in the micro-ejection unit, liquid line and pump. Independent claims are also included for: the system for receiving and/or releasing liquid samples; and a process for synchronizing a system for receiving and/or releasing liquid samples using the computer. Preferred Features: The micro-ejection unit comprises an end piece (5) as micro-ejection pump or a piezo-micro-pump or comprises an end piece as disposal pipette tip, an impulse generator and a liquid line. The pump is a piston pump consisting of a cylinder (11), a piston (12) and a drive (13).

Abstract: The invention concerns a computer (4), a computer program product, and a method for synchronizing a system for aspirating and/or dispensing liquid sa m- ples that comprises a microejection device (1) and a pump (2) which are con- nected with one another via tubing (3), with this computer (4) being imple- mented for loading an activatable computer program product for synchronizing the microejection device (1) and pump (2). The computer (4), computer pro- gram product, and method are characterized in that the computer (4) is made capable, on the basis of the loaded and activated computer program product, of controlling and synchronizing the following functions of this system: .cndot. Active definition of a sample volume and dispensing of this defined sample volume with the microejection device (1), which is filled with sample liquid ; .cndot. Tracking of a part (12, 12', 12"), which conveys the liquid, of the pump (2) around a value, dependent on this sample volume, which is defined and is actively dispensed only by the microejection device (1), to prevent excessiv e pressure differences in the microejection device (1), tubing (3), and pump (2). The invention also includes a corresponding system for performing this metho d.
