1. A method for detecting a phase separation of a waterborne or solvent-borne or solvent-free coating composition comprising
providing the coating composition in a receptacle;
providing a measurement instrument for receiving the receptacle, the measurement instrument comprising a measurement probe;
controlling the measurement instrument to
a) displace the measurement probe through the coating composition along a predefined measurement path with a predefined speed profile, the predefined measurement path extending along a length axis of the receptacle,
b) acquiring a force-displacement profile by measuring a force exercised on the measurement probe while the probe is being displaced along the predefined measurement path with the predefined speed profile;
processing the force-displacement profile for detecting at least one phase separation of the coating composition; and
outputting a detection result.
