The standard treatment is 5ml per seam irrespective if it is a double or single brood colony.
It is not necessary to separate the two boxes in a double brood colony.

The 5 ml trickle has to be carried out for each occupied comb space in a double brood box situation. I quoted Ian Craig’s wintering method of 8 frames/brood box. Jon’s recommended procedure would have Ian’s bees underdosed by some 35mls: A potentially dangerous situation if all 14 bee spaces are occupied. In Ian’s system this is a distinct possibility.
