h) Mixing Chamber
A chamber constructed of glass, PTFE, or other nonreactive material
and designed to provide thorough mixing of reaction products and di-
luent air. The residence time is not critical when the dynamic parameter
specification is met.
i) Output Manifold
The output manifold should be constructed of glass, PTFE, or other non-
reactive material and should be of sufficient diameter to insure an in-
significant pressure drop at the analyzer connection. The system must
have a vent designed to insure atmospheric pressure at the manifold
and to prevent ambient air from entering the manifold.
