A METHOD FOR DETECTING THE INTERFACE BETWEEN TWO ADJACENT BATCHES OF GASOLINE SUCCESSIVELY FLOWING THROUGH A CONDUIT WHICH COMPRISES INJECTING A MISCIBLE FLUORINATED HYDROCARBON ADJACENT TO SAID INTERFACE IN AN AMOUNT BETWEEN ABOUT 0.1 AND ABOUT 500 P.P.M. OF THE GASOLINE AND SUBSEQUENTLY DOWNSTREAM FROM THE POINT OF INJECTION REMOVING A PORTION OF THE GASOLINE CONTAINING SAID FLUORINATED HYDROCARBON, VAPORIZING SAID PORTION OF THE GASOLINE THUS REMOVED AND DETERMINED THE PRESENCE OF FLUORINATED HYDROCARBON IN SAID GASOLINE.
