Pneumatic flow through the O
under pressure. The zero air source must be capable of maintaining a continuous flow rate
of at least 100 cm
which case the minimum continuous flow rate must be at least 1.1 SLPM.
Input and output gas flow is directed by two valves, both of which must be open:
•
•
The rate of flow through the O
assembly positioned between the O
self-adjusting pressure regulator on the zero air (diluent ) supply gas line maintains the
pressure across the critical flow orifice of the flow control assembly
