Safety Practices for Flame Atomization
•
Regularly check for leaks at joints and seals using an approved leak test
solution.
•
When you perform any maintenance or installation procedures, follow the
instructions in the guide exactly.
•
Do
not
attempt to service the gas control system yourself. A PerkinElmer
service engineer, or similarly authorized and trained person, must perform
the work.
•
When you shut down the instrument, for example at the end of the working
day, shut all the gas lines at the cylinder or regulator valves. Bleed the lines
between the regulator and instrument to atmosphere before switching off
the ventilation system.
Air Supply
An air compressor is recommended for the air supply to the burner system.
Cylinders of compressed air should only be used as an emergency or short-term
solution.
•
If you use cylinder air, make sure that it is compressed air and not oxygen-
enriched air (e.g. breathing air); the use of oxygen-enriched air can cause
a flashback of the flame.
•
Never
use oxygen as the oxidant since this can cause an explosion.
Nitrous Oxide (dinitrogen monoxide, N
2
O)
•
Tubing and fittings carrying nitrous oxide must be free of all oil, grease,
and organic materials. Spontaneous combustion may occur if nitrous oxide
comes into contact with these materials.
•
Use a double-stage or heated regulator for nitrous oxide to prevent freezing
of the diaphragm and a loss of pressure regulation.
•
Do
not
store nitrous oxide in close proximity to flammable gases, such as
acetylene or hydrogen.
