Abstract:
1. A microfluidic system comprising: a first channel containing at least two fluid slugs, wherein diffusion regions are formed between adjacent miscible fluids of adjacent fluid slugs, the at least two fluid slugs including the diffusion regions moving along the first channel toward a second channel; the second channel intersecting the first channel; a monitoring device that identifies and tracks one or more diffusion regions between adjacent miscible fluids of two or more miscible fluid slugs moving along the first channel; a fluid flow control system that controls the flow of fluid through each of the first and second channels; and wherein as two or more fluid slugs including diffusion regions are moved through the first channel, the fluid flow control system causes the one or more diffusion regions moving along the first channel to flow past an opening of the second channel along the first channel and causes a portion of a slug that is substantially free from contamination by an adjacent fluid slug present in the first channel to be collected into the opening of the second channel.
