Sulfur response signal enhancement assembly of flame photometric detector and application thereof

The invention provides a sulfur response signal enhancement assembly of a flame photometric detector. The sulfur response signal enhancement assembly is composed of a quartz rod, a circular porous baffle, a T-shaped cylinder and a metal ring which are coaxially arranged, the metal ring sleeves the quartz rod, and the distance from the lower end of the quartz rod to a nozzle is adjusted by changingthe position of the metal ring on the quartz rod. The circular porous baffle plate of the response signal enhancement assembly is fixed between a flame photometric detector combustion chamber and anexhaust hole cover, and the circular porous baffle does not influence the emission of the gas in the combustion chamber. The response signal enhancement assembly has the following advantages that thetemperature of flame is reduced by the placed quartz rod, the light-emitting area of sulfur in the flame is increased, and then the sensitivity of sulfide detection is improved; the mechanical structure of the assembly is simpl
