Burner is a device that makes fuel and air spray out in a certain way for mixed combustion. Burner is divided into industrial burners, burners, civil burners, and special burners according to type and application field. It is mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or metal titanium. The function of the burner is to atomize the specimen by flame combustion. The atomized test solution enters the burner, and under the action of flame temperature and flame atmosphere, after drying, melting, evaporation, dissociation and other processes, a large number of ground state atoms, as well as partially excited state atoms, ions and molecules. A well-designed burner should have high atomization efficiency, low noise, and flame stability to ensure high absorption sensitivity and measurement precision. Gap burners are commonly used in atomic absorption spectroscopy to produce atomic vapor. According to the different types of gas and auxiliary gas used, the length and width of the burner gap are different, and the general burner is marked with applicable gas and auxiliary gas.
