ABSTRACT:
The invention relates to a method of detecting the presence of a liquid introduced into a mix of constituents. The method comprises the following steps:excitation of the mix by a light signal in the absence of the liquid to be detected;measurement of a fluorescence signal over a time Δt characteristic of the liquid to be detected, so as to produce a reference quantity Ro;introduction of an amount of liquid to be detected in the mix;excitation of the mix by a light signal;measurement of a fluorescence signal over a time Δt so as to produce a quantity R;comparison of the quantity R with a quantity k×Ro.The invention applies to the detection of serum pipetting errors within the context of bioassays, especially immunological tests.
