Abstract: An apparatus for preventing backflow and contamination, and detecting by-pass leaks in a flow control arrangement is disclosed. The apparatus includes a vent line connecting a sweep gas source and a vent. Constant process-inert gas flows from the source through the vent line into the vent.
