(AA) Burner Maintenance (AA-7800F,7000F, AA-7800F/AAC,7000F/AAC)

When foreign objects such as dirt and contaminants adhere to the burner head, nebulizer or chamber interior, the indicated value becomes unreliable and absorbance sensitivity is decreased. It is recommended that these burner components be periodically cleaned.

 

WARNING:

  • Wear protective goggles and protective gloves to maintain the burner head.
    If chemicals get into the eyes, there is a risk of loss of sight.

  • Do NOT remove parts inside the burner compartment during flame combustion.
    Otherwise there will be a risk of gas leakage or flashback.
  • Check that an O-ring is fitted, and check that the O-ring is not damaged or deformed.
    If no O-ring is fitted, or if the O-ring is damaged or deformed, it could cause an accident.
    To replace the O-ring, contact your Shimadzu representative.
