METHOD OF DETECTING THE PRESENCE OF A LIQUID IN A MIX

摘要

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 DELTA t 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 DELTA t so as to produce a quantity R; comparison of the quantity R with a quantity kxRo. The invention applies to the detection of serum pipetting errors within the context of bioassays, especially immunological tests.
