What hasn't been possible yet ...
If a particular peak must not reach the second column once it has left the first column, an
output is required between the two columns (cut output). Furthermore, a connection is
required for the pressure P2 from the "thought experiment" above. The solution to the
problem is the live T-piece.
The two columns are connected in the live T-piece via a capillary
①
. This coupling capillary
has a flow resistance; two pressures must be considered:
● P3 downstream of the capillary
● P2 upstream of the capillary.
In "straight operation", everything remains as described in the section "Pressures and flows".
Only the pressure P3 must be additionally considered.
