Abstract

A method for controlling pipetting operations done by a pipetting device having a system for measuring the flow rate of the liquid suctioned or dispensed and electronics to communicate with a computer. The method is based on detection of flow rate variations and the moments at which those variations occur. The method includes obtaining a curve of liquid flow rate by the pipette as a function of time, computing the first deviation of the curve, identifying and recording the maximum and minimum values of the first deviation and the moments at which the maximum and minimum values occur, comparing the maximum and minimum values and the moments at which the maximum and minimum values occur with predetermined references for the values and the moments at which they occur, and based on the result of the comparison, providing a validation or error message.
