ABSTRACT:
A burner is disclosed which can be used in an apparatus for analyzing a gas omposition by flame spectrophotometry, comprising, disposed coaxially with each other, a tubular body having an open end on which an optical system is mounted coaxially, a sample taking nozzle which extends the body while defining an intake chamber, a collar fast with the body through which passes a tubular chimney, a nozzle for intake of the gas composition which is fitted in the chimney while forming therewith an annular intercalary chamber into which opens a fuel gas intake duct and a capillary tube for intake of the gas composition to be analyzed, this capillary tube being connected to the intake duct at the level of its end situated in the intake chamber.
