Abstract: A system for sample analysis, comprising:at least one droplet generator that forms a plurality of emulsions including droplets of partitioned samples, the samples being prepared as reaction mixtures for amplification of a nucleic acid target;a plate defining an array of cavities to hold the emulsions;a heating and cooling device to heat the emulsions disposed in the cavities to induce nucleic acid amplification in droplets of the emulsions;a detection assembly to detect signals from intact droplets of the emulsions;a fluid transfer device including an autosampler configured to transfer droplets from each of the cavities to a detection site of the detection assembly; anda controller in communication with the detection assembly and programmed to estimate a presence, if any, of the nucleic acid target in the samples based on signals detected from the intact droplets.
