METHOD, COMPUTER PROGRAM, AND APPARATUS FOR DETECTING PIPETTING ERRORS

摘要

Method for detecting pipetting errors comprising the steps of:
- during pipetting, measuring the pressure in the tip of a pipetting device and determining an earlier rate of change of the pressure ´ 0 in the tip;
- based on the earlier rate of pressure change ´ 0 and a previous pressure value p i , determining an expectation range for the pressure p i +1 at a further moment in time and/or an expectation range for the rate of pressure change ´ i +1 based on the pressure at the further moment in time t i +1 ;
- at the further moment in time t i +1 measuring the pressure p i +1 in the tip;
- determining the occurrence of a pipetting error by comparing the measured pressure p i +1 at the further moment t i +1 in time and/or a rate of pressure change ´ i +1 calculated on the basis of the pressure p i +1 at the further moment t i +1 in time, with respectively the determined expectation range of acceptable pressures and the determined expectation range of acceptable rates of pressure change.
