Abstract: AN ANALYTICAL INSTRUMENT INCLUDING A FLAME SOURCE AND A DETECTION SYSTEM FOR THE QUALITATIVE AND QUANTITATIVE EMISSION OR ABSORPTION ANALYSIS OF A SAMPLE. THE SAMPLE IS ATOMIZED AND MIXED WITH AN APPROPRIATE FUEL GAS, AND THE MIXTURE IS LED THROUGH AN ANGULARLY DISPOSED BURNER BARREL TO A GRID FOR HOLDING THE FLAME. COMPRESSED AIR IS SUPPLIED TO THE ATOMIZER, AND A PORTION OF THE AIR IS DIRECTED TO A VENTURI NOZZLE WHICH IS CONNECTED TO A SUPPLY OF THE FUEL GAS. THE AIR IS EFFECTIVE TO DRAW THE FUEL GAS THROUGH THE VENTURI AND INTO THE ATOMIZER AT A SUBSTANTIALLY CONSTANT RATE IRRESPECTIVE OF PRESSURE FLUCTUATIONS IN A GAS SUPPLY. THE INSTRUMENT ADDITIONALLY INCLUDES A SCREEN AND BAFFLE CONSTRUCTION WITHIN THE ANGULARLY EXTENDING BARREL WHICH IS EFFECTIVE TO DIRECT LARGE DROPLETS OF SAMPLE MATERIAL AWAY FROM THE BARREL INLETS.
