Cleaning the Burner System

The nature of the samples aspirated determines how frequently you need to clean the burner
system.
•
The burner should provide an even flame over the length of the burner slot. An uneven
flame may indicate that the slot needs cleaning. A badly clogged slot may cause a flashback
of the flame.
•
Aspirating samples with high solids content may cause deposits to build up along the burner
slot.
•
Prolonged operation of the nitrous oxide-acetylene flame may cause deposits of pyrolytic
carbon to build up along the burner slot.
Unstable acetylides, which are likely to explode when dry, may be formed when
aspirating high concentrations of silver, copper, or mercury salts into an
acetylene flame.
