46 Agilent 55B AA Spectrometer User’s Guide
Burner
There are two types of burner available for use with your Agilent AA system: an air-
acetylene burner or a nitrous oxide-acetylene burner.
Both burners include an interlock key designed to prevent ignition if either a burner
is not fitted, or a burner is fitted which is not suitable for the selected flame type. A
handle enables you to rotate the burner so that it aligns with the optical path. The
burner can also be adjusted vertically and horizontally by rotating the adjustment
knobs found on the front face of the burner adjuster.
The burners are identified by their labels and dimensions of the burner slot:
Air-acetylene burner: 10 cm slot length.
Nitrous oxide-acetylene burner: 6 cm slot length.
Instructions on how to Nebulizer burners are in the Maintenance section - see
Page 93.
CAUTION
Only Mark VI A or Mark 7 burners should be used with this system. Previous
versions should not be installed.
WARNING

Improper or careless use of burners can create explosion hazards and fire
hazards which can cause death, serious injury to personnel, and damage to
equipment and property. Whenever you handle a burner, remember that it
may be very hot.

Never attempt to use an air-acetylene burner with a nitrous oxide-acetylene
flame, this will cause a flashback.
