Introduction to the burner

A burner is a general term for a device that makes fuel and air eject and mix and burn in a certain way. Burners are classified into industrial burners, burners, civil burners and special burners according to their types and application fields. 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 sample through flame combustion. The atomized test solution enters the burner. Under the action of flame temperature and flame atmosphere, a large number of ground-state atoms, as well as some excited-state atoms, ions and molecules are generated through processes such as drying, melting, evaporation, and dissociation. A well-designed burner should have high atomization efficiency, low noise, and flame stability to ensure high absorption sensitivity and measurement precision. Slot burners are commonly used in atomic absorption spectrometry to generate atomic vapors. Depending on the type of gas and auxiliary gas used, the length and width of the burner gap are different. Generally, the applicable gas and auxiliary gas are marked on the burner.
