Liquid distribution method and immunoassay method

Abstract

A liquid distribution method comprises: providing at least two ferrying units, each ferrying unit made to reciprocate between an initial workstation and a first workstation; transferring from the initial workstation onto each ferry unit a reactor containing a sample; at the first workstation, adding a reagent into the reactor; recording, as a first cycle, a shortest time window during which a sequence of actions performed by each ferry unit can be cyclically reproduced, and recording, as a second cycle, a quotient obtained by dividing the first cycle by the number of ferry unit, and successively transferring the reactors to other ferry units staggeredly at intervals of the second cycle; and sequentially removing from the ferry units the reactors for which the mixing has been completed, staggeredly at intervals of the second cycle, and placing another reactor containing the sample onto the ferry unit from which the reactor was removed.
