A microfluidic device performs a method of partitioning droplets from a fluid reservoir containing particles that provides a non-Poissonian distribution of dispensed droplets containing a desired number of particles. Using an electrowetting on dielectric (EWOD) device, droplets are dispensed having a Poissonian distribution of dispensed droplets containing a desired number of particles, and the droplets are interrogated to determine whether each dispensed droplet has a desired number of particles. Droplets that contain the desired number of particles are moved by EWOD operation to a reaction area on the EWOD device, and droplets that do not contain the desired number of particles are rejected and moved by EWOD operation to a holding area on the EWOD device that is different and spaced apart from the reaction area. The result is that droplets in the reaction area have a non-Poissonian distribution of droplets containing the desired number of particles.
