Questions on switching cls from active to passive.

[20181002_162819] Heres a pic of a hybrid passive unit. The n2 stays in the headspace of the injection tank like a spring to move the liquid, after injection and recovery of 90%of the liquid the recovery pump is turned on to scavange any remaining gas. All is returned to one of the tanks, then re injected with the next column.

this works pretty good for not disconecting any hoses, full mantifold and n2 assist -80c chiller and acetone for blood!
