A soft and resilient, cold-water dispersible polyurethane foam suitable for disposable personal care products is produced by the combination of corn syrup, glycerin, polyether diamine, PEG, a diisocyanate, water and a catalyst. The Means for processing computer instructions includes means for receiving computer instructions and means for executing computer instructions. The output element is functionally connected to a crankshaft of the internal combustion engine in order to introduce a crankshaft torque therein. By implementing a filter at the corresponding frequency, data having that frequency will be transmitted. The switching control circuitry is coupled to receive the state command signal from the transient minimizer circuitry. One or more common fluid supplies may be utilized in each of the sample preparation and separation steps to minimize the number of requisite fluid connections and external components such as pumps, reservoirs, pulse dampers, flow controllers, and the like.
