Safety Practices for Electrothermal Atomization
•
To avoid serious burns, never touch the burner head until it has cooled to room
temperature.
UV Radiation
The flame, especially the nitrous oxide/acetylene flame, emits ultraviolet radiation.
•
Keep the atomizer compartment door closed when the flame is burning and
never directly view the flame unless you are wearing UV-absorbing glasses.
Acetylides
If you have aspirated high concentrations of copper, silver, or mercury solutions
into an acetylene flame, unstable acetylides may have formed in the spray chamber.
If permitted to dry, these compounds may explode.
•
Aspirate solution continuously to prevent residues from drying.
•
Thoroughly flush the spray chamber and drain system with water immediately
after such an analysis.
Cyanide Solutions
If you intend to aspirate cyanide solutions, make sure that the pH of the liquid in
the drain vessel is greater than pH 10; toxic hydrogen cyanide gas is formed when
cyanides contact acidic solutions.
•
Never allow solutions containing cyanides to mix with acidic solutions.
Safety Practices for Electrothermal Atomization
Safety Interlocks
PerkinElmer provides a number of safety interlocks on the graphite furnace
(electrothermal atomization) system that monitor the gas pressure and the
temperature of certain system components.
•
Do not attempt to defeat these interlocks; you may compromise your own, or
someone else's, safety.
