Atomic Absorption Spectroscopy can be maintained from light sources, atomization systems, optical systems, pneumatic systems, etc.
1, light source
Hollow cathode lamps should be used within the maximum allowable operating current;
2, Atomization system
After each analysis operation, especially after analysis of excessively high concentration or strong acid sample, spray distilled water for several minutes immediately to prevent the atomization tube and burner head from being contaminated or rusted.
The optical components of the external light path are often kept clean and are usually cleaned at least once a year
4, Gas system
Inspect gas leak detection, especially acetylene gas leakage may cause accidents
