Abstract
A method for dispensing precise quantities of reagents is disclosed including the steps of providing positive displacement syringe pump in series with a dispenser, such as a solenoid valve dispenser. The pump is controlled by a stepper motor or the like to provide an incremental quantity or continuous flow of reagent to the dispenser. The dispenser is operated in accordance with predetermined parameters to dispense droplets of reagent onto a target substrate at the metered flow rate.
