ABSTRACT:
A system for analyzing particles from compressed gas. The system employs a back-filling technique to slowly balance the pressures on both sides of a control valve before operation. Use of a critical orifice as a flow control device for compressed gases of varying pressure is employed to provide a constant volumetric flow rate and thus a constant residence time within an impurity sensor.
