Abstract

Abstract ABOUT TWELVE PERCENT OF THE INSIDE DIAMETER OF THE CHIMNEY. TO CLEAN THE PORTION OF THE INLET CONDUIT WHICH EXTENDS INTO THE ATOMIZING HOUSING, A WIRE AND TUBE ASSEMBLY IS MOVABLY POSITIONED WITH RESPECT TO THE HOUSING, SUCH THAT THE WIRE MAY BE INSERTED WITHIN THE CONDUIT PORTION WHILE THE TUBE SURROUNDS THE CONDUIT TO PROVIDE SUPPORT. IN SOME EMBODIMENTS THIS CLEANING IS ACCOMPLISHED AUTOMATICALLY IN REPSONSE TO THE CHANGING OF THE SAMPLE. AN ANALYTICAL INSTRUMENT INCLUDING AN ATOMIZER-BURNER AND A DETECTION SYSTEM FOR THE QUALITATIVE AND QUANTITATIVE EMISSION OR ABSORPTION ANALYSIS OF A SAMPLE. THE SAMPLE IS INTRODUCED THROUGH AN INLET CONDUIT INTO A HOUSING AND IS ATOMIZED AND MIXED WITH AN APPROPRIATE FUEL GAS. THE MIXTURE IS LED THROUGH AN ANGULARLY DISPOSED BURNER BARREL AND A FLUID DISCHARGE OPENING TO A GRID FOR HOLDING THE FLAME. A CHIMNEY IS SUPPORTED IN SPACED RELATIONSHIP WITH THE DISCHARGE OPENING SUCH THAT THE SPACING BETWEEN THE CHIMNEY AND THE WALL WHICH FORMS THE OPENING PREFERABLY IS NOT LESS THAN ABOUT SIX PERCENT AND NOT GREATER THAN
