Abstract: Systems, methods, and software program products for dispensing chemical solutions. A controller receives a signal from a pressure sensor indicative of a pressure of a diluent. The controller determines an expected flow rate of the diluent through an eductor based at least in part on the pressure of the diluent. The controller may further determine an expected concentration of a chemical product in the solution dispensed from a discharge port of the eductor. Based on the expected flow rated and concentration of the chemical product, the controller determines a duration of a dispense stage of a dispensing operation required to dispense a predetermined dose of the chemical product. The controller then causes the diluent to flow through the eductor for the determined duration of the dispense stage. A check valve on the output of the eductor prevents dissimilar chemicals from mixing and reduces a response time of the eductor.

A closed loop air supply system is used for dedusting devices providing a final removal of dust and debris from the stored product before being delivered to the ultimate utilization facility.

Abstract: Provided are methods and systems for dispensing different chemicals used for high productivity combinatorial processing. A dispense panel may include multiple inlet lines for supplying different chemicals. Each inlet line is connected to its own three-way valve that either allows the supplied chemical to flow from the inlet line towards a dispense valve connected to a dispense manifold (during dispensing of the supplied chemical) or allows another chemical to flow from the dispense valve to a waste manifold (during priming of the dispense manifold with this other chemical). Specifically, during priming a chemical supplied from its inlet line and is passed through a corresponding three-way valve and is directed to its dispense valve and then into the dispense manifold. Other dispense valves and three-way valves of the dispense panel allow this chemical to flow out of the dispense manifold, thereby priming remaining parts of the panel.
