An emulsion shock mixes the gas with the oil.
A floating piston shock "compartmentalizes" the gas and oil as you suggest. The gas is under high pressure on one side of the floating piston and the oil is on the other side of the floating piston. The "valving piston" travels through the oil, and is connected to the shiny chrome rod (shaft).
A third type uses a gas filled bag that is inserted into the shock body.
