Abstract:
A system for achieving a controlled low emission rate of small volumes of liquid solutions comprising:a sealed liquid solution reservoir having an outlet port; said liquid solution reservoir having a small volume capacity in the range of 1-100 Ml; a self-powered fluid delivery micropump having means for pumping a liquid solution out of said outlet port of said liquid solution reservoir; a collector for receiving a liquid solution from said sealed liquid solution reservoir and for emitting the liquid solution from said collector; said collector having means for producing an emanation rate from said collector that exceeds the fluid delivery rate from said fluid delivery micropump to said collector thus achieving a zero-order emission without accumulation of said liquid solution on said collector and resulting in an emission rate that is constant in time; means for opening said outlet port of said sealed liquid reservoir; means for transmitting said liquid solution from said outlet port of said liquid solution reservoir to said collector; and means to initiate operation of said micropump.
