Abstract
Abstract The invention relates to a method and an apparatus for luminescence measurement of samples in transparent multi-well plates or strips. A luminescence instigating reagent is added to the samples in sequence to instigate a luminescence reaction in each sample, and the resulting photon emission from each well is measured during a predetermined measurement period. According to the invention an on-going luminescence reaction is actively interrupted atthe end of the measurement period before a corresponding reaction is instigated in the next sample.
