Nebulizer - Agilent Technologies AA Series User Manual

Safety Practices and Hazards
Burner interlocks are incorporated to minimize the possibility of
using the wrong burner. Never interfere with or attempt to bypass
any interlock fitted to this instrument.
To minimize the rate of burner blockage, the burner slot must be
cleaned and polished as described in the Maintenance section.
Never allow burners to become blocked. Progressive burner blockage
can increase the static pressure in the liquid trap to the point at
which the liquid seal is breached. This can cause a flashback and
create an explosion hazard or a fire hazard.
Never allow carbon to build up on the slot, as glowing particles can
dislodge and fall through the slot, causing a flashback.
Always turn the flame off before attempting to clean the burner slot.
Never clean the slot of a burner while a flame is running.
Never leave a flame unattended.
Never disassemble or modify a burner. Never use a damaged burner.

Nebulizer

Incorrect assembly and fitting of nebulizers to an atomic absorption
spectrometer can create explosion hazards and fire hazards which
can cause serious injury to personnel and damage to equipment and
property.
Ensure that the nebulizer is correctly assembled and correctly fitted
to the spray chamber before lighting the flame. Nebulizers should be
correctly adjusted before lighting the flame.
Never remove a nebulizer from the spray chamber while the flame is
on, and do not use a mechanical device (for example, a wire) to clean
the capillary of a nebulizer while a flame is operating. Always
extinguish the flame before removing the nebulizer from the spray
chamber.
Regularly test all connections for leaks. Rectify all leaks before
lighting the flame.
