In various exemplary embodiments, a system and associated method to provide customized combination package best offers is disclosed. Cavities and channels, which connect these cavities to one another and which transport, based on the capillary effect, liquids required for carrying out analysis and synthesis, are arranged inside the microfluidic chip. In comparison with prior art systems, the systems presently disclosed provide one or both of more accurate measurements for the same amount of space, and smaller space requirements with the same or better accuracy. A circuit board, or other suitable component, contains a plurality of electrical circuits and is secured within the housing.
