Upward flux - representative colocated PAT sampling

The same geometrical IDE solution can be effectuated by several alternative but more complex valve designs. A recent analysis of the issues of severely incorrect sampling valve design and effects for horizontal flow can be found in [20], 

This configuration has the important added benefit of ensuring significantly improved mixing of the reactor contents. This feature cannot be over-emphasized. While the upward flow sampler originally was designed 

The self-mixing up-streaming recirculation loop ranks as the prime example of the SUO lot transformation in which a 3-D lot (reactor) has been turned into an easy to sample 1-D configuration (pipeline).
