Cleaning the burner chamber after aspirating
solutions containing Cu, Ag, or Hg
If you have aspirated high concentrations of copper, silver, or mercury solutions into an acetylene
flame, unstable acetylides may have formed in the burner chamber. If permitted to dry, these
compounds may explode.
1. Aspirate dilute acid (1% (v/v) HCl solution) for 5 minutes before turning off the flame.
2. Extinguish the flame and allow the burner head cool.
3. Remove the burner head.
4. Pour about 500 mL of deionized water slowly through the neck of the burner chamber to
thoroughly flush the chamber and the drain system.
5. Empty the drain vessel.
NOTE: Dispose of hazardous or corrosive solutions properly and refer to your local safety regulations
for proper disposal procedures
