<p>A computer-controlled pipetting apparatus for liquid samples, has a memory for storing a real measured test curve and a simulated curve, and a programme enabling the processor to generate the simulated curve, fit the real curve to this by an iteration process and then assign decision qualities to the pipetting process using parts of the real curve which differ from defined threshold values on the iterative curve. Pipetting apparatus (1) comprising: (a) a pipette tip (2) for liquid samples; (b) a pump (4) for producing reduced or elevated pressure in the tip (2), attached to (2) by a pump line (3); (c) a fluid space (5) defined by (2) and/or (3); (d) a test probe (6) connected to (5) for acquiring physical parameters during pipetting; and (e) a control unit (7) with a processor (8) in which an activated computer programme controls the apparatus (1) so that individual pipetted samples are accepted or rejected on the basis of the detected parameters. This apparatus also has: (f) a memory unit (9) for storing a real measured test curve (41) and a simulated curve (42) for such a pipetting process; (g) a computer programme product which, when activated, enables the processor (8) to generate the simulated curve (42) and approximate the real curve (41) to this by an iterative process so as to produce an iterative curve (43), and then assign one of several decision qualities to the pipetting with the aid of parts of the curve (44) in the real curve (41) which differ from defined threshold values (45) with regard to corresponding parts (46) on the iterative curve (43).</p> |
