System for accurately weighing solids and control mechanism for same
Patent 8,156,957
A system, including a closed chamber (20) having a gas inlet (22) and a gas outlet (24) is shown and described. An inert gas supply under positive pressure is connected to the gas inlet, and a bubbler is connected to the gas outlet. The bubbler includes a compartment that is partially filled with liquid so as to define a head space, an inlet operatively connected to the gas outlet, a vent, and a vacuum line in fluid communication with the head space so that the head space has a negative pressure.
