Presets
Design Notes
Buffer → D: No isolated path to D. V1+V2+V3+V5 also opens B/C flow path.
Sample → D: No isolated path to D. V2+V3+V5 also opens B/C flow path.
Buffer/Sample → BC simultaneous: B/C share a junction and U-path connection. Unequal flow distribution likely. Sequential B then C operation recommended.
Pullback mapping (sample front-end divert):
Sample A → Pullback line
Sample B → Sample bypass
Sample C → Sample bypass
Sample AB → Pullback line
Sample BC → Sample bypass
Sample ABC → Pullback line
Sample ABCD → Pullback line
