Zusammenfassung:	According to an example aspect of the present invention, there is provided a liquid handling system for dispensing a liquid sample from a tip. The system comprises a light source configured to project a first beam of light via a first optical path that interacts with the tip or its contents, and further configured to direct a second beam of light via a second optical path that does not interact with the tip and its contents; a first detector configured to detect the first beam of light; a second detector configured to detect the second beam of light; an analysis unit configured to analyse a state of the tip on the basis of signals obtained from the first and second detectors; wherein the second detector is a normalization detector configured to measure intensity of the light source.
