Abstract
A method for detecting a liquid surface of a liquid sample with a pipetting tip, the method includes receiving an indication of a capacitance of the pipetting tip, and determining, based on a rate of change of the indication of the capacitance rising above a first preselected threshold, that the pipetting tip has come into contact with the liquid surface. The method also includes determining, based on the rate of change of the indication of the capacitance falling below a second preselected threshold, that the pipetting tip has lost contact with the liquid surface.
