Abstract
Abstract A COLORIMETER FLOW CALL WITH OPPOSED WINDOWS FOR THE PASSAGE OF A LIGHT BEAM. THE CELL IS DIVIDED IN TWO CHAMBERS BY A WALL EXTENDING PARALLEL TO THE LIGHT BEAM. LIQUID ENTERS THE FIRST CHAMBER AND FLOWS TO THE SECOND CHAMBER THROUGH UPPER AND LOWER APERTURES IN THE WALL. GAS IS SEPARATED FROM THE LIQUID IN THE FIRST CHAMBER AND PASSES TO AN OUTLET FROM THE SECOND CHAMBER WITHOUT INTERFERING WITH THE LIGHT BEAM, AS THE WINDOWS ARE AT A LOWER LEVEL THAN THE UPPER APERTURES.
