Abstract: A METHOD FOR PRODUCING AN AEROSOL STREAM OF AN INORGANIC COMPOUND OF AN ELEMENT COMPRISES INTRODUCING A COMPOUND OF THE ELEMENT SUCH AS SODIUM CHLORIDE, IN SOLUTION OR POWDER FORM, INTO A FLAMMABLE GAS STREAM, SUCH AS AN OXYACETYLENE MIXTURE, TO FORM A SUSPENSION OF THE COMPOUND INTRODUCED THERETO, THE FLAMMABLE STREAM HAVING A FLAME TEMPERATURE NOT LESS THAN THE VAPORIZING TEMPERATURE OF THE COMPOUND INTRODUCED, IGNITING THE FLAMMABLE STREAM WHEREBY THE SUSPENDED COMPOUND IS VAPORIZED AND ALLOWING THE IGNITED STREAM TO COOL AT LEAST TO THE TEMPERATURE AT WHICH THE INORGANIC COMPOUND CONDENSES THEREFROM TO FORM THE AEROSOL STREAM. THE AEROSOL STREAM HAS ONE APPLICATION IN THE TESTING OF AIR FILTERS, THE EFFLUENT FLOW FROM WHICH CAN BE PHOTOMETRICALLY ANLAYZED. FOR THE PRODUCING AEROSOLS TO BE SUBJECTED FO PHOTOMETRIC ANALYSIS THE COMPOUND INTRODUCED INTO THE GAS STREAM IS A COMPOUND OF A METAL SELECTED FROM THE ALKALI METALS, THE ALKALINE EARTH METALS AND ZINC.
