Abstract: An apparatus and a method for analyzing a plurality of samples according to an analysis protocol is described, wherein each of the samples is contained within a liquid test package comprising a plurality of liquid and air segments including a reagent segment and wherein during at least a portion of the protocol the reagent segment emits photons. At least one of the liquid test pack includes a buffer segment separated from the reagent segment by a vanish bubble. The apparatus comprises a fluid conduit through which the liquid test packages are flowed, a first luminometer positioned along the fluid conduit for detecting photons emitted by the reagent segment of the at least one of the liquid test packages, a second luminometer positioned along the fluid conduit for detecting photons emitted by the reagent segments of the liquid test packages other than the at least one of the liquid test packages, and a vanish zone contained within the fluid conduit between the first and second luminometers.
