Method and Device For Checking Whether a Liquid Transfer Has Been Successful

Abstract

The invention relates to a method for checking whether the transfer of liquid samples has been successful. In said method, a pipetting system or a dispensing system is made to transfer a liquid sample (1) at a specific location (2), and it is verified whether said liquid sample (1) has actually been transferred. The inventive method is characterized in that a distribution image (4) of the intensity of the heat radiation released by said specific location (2) is recorded once the liquid sample (1) has been transferred. Said method can be used in a pipetting system or a dispensing system by making such systems dispense or accept a liquid sample (1) and then checking whether said liquid sample (1) has actually reached or been accepted at the specific location (2). According to the invention, this is achieved by the fact that a distribution image (4) of the intensity at least of the inherent heat radiation released by the specific location (2) is recorded by means of an infrared camera (12) once the liquid sample (1) has been transferred and is compared to a distribution image (4′) of the intensity of the heat radiation of said location (2) or the surroundings (5) thereof, which is recorded before the liquid sample (1) is dispensed or accepted.
