Abstract
Methods for determining one or more operating parameters for a timing protocol of a microfluidic circuit are provided. In some embodiments, wet out times are measured for certain flow channels, and start times, flow rates and/or other parameters are calculated so that the various fluids in the microfluidic cartridge arrive at certain locations at a desired time and/or in a desired sequence. To help compensate for process variations, one or more fluidic process monitor components/structures may be fabricated along with the functional components/structures of a microfluidic cartridge. Test may be performed on the process monitor components/structures to help identify process variations in the particular microfluidic cartridge at hand. By using the process monitor data, the timing protocol for a particular microfluidic cartridge may be made more accurate.
