Agilent Technologies AA Duo
Agilent Technologies · Model AA Duo
Simultaneous operation of flame and graphite furnace doubles your productivity Combine flame or hydride atomizers with either a deuterium or Zeeman-corrected graphite furnace Dedicated atomizers eliminate setup and changeover times, saving valuable time Widest linear dynamic range, from sub parts-per-billion to percent levels, allows analysis of any sample Each atomizer is aligned for immediate use and never needs re-alignment, enabling true set-and-forget optimization Take advantage of the Agilent AA Fast Sequential technology, which provides the world's fastest flame AAS The Agilent AA Duo is controlled by Agilent Worksheet Software, which minimizes training by delivering rapid instrument set-up, easy operation, and simple method development for novice and expert users.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Low lamp / signal energy
HighSymptoms: Hollow-cathode lamp energy low, peak search fails, poor sensitivity.
Root cause: Aged hollow-cathode lamp, dirty optics, or lamp-turret misalignment.
Flame instability / burner fault
HighSymptoms: Flame lifts, flashes back, or will not light; noisy signal.
Root cause: Blocked nebuliser or burner slot, incorrect fuel/oxidant flows, or a gas-control fault.
Furnace atomizer fault (graphite furnace mode)
MediumSymptoms: Formation factor out of range, poor atomization, tube fails quickly.
Root cause: Graphite tube at end of life, worn furnace electrode contacts, or a furnace power / thermal fault.
Autosampler dosing fault
MediumSymptoms: Inconsistent injection volume, spilled sample, arm misalignment.
Root cause: Autosampler dosing tip / pump or arm alignment.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Low energy / peak search fails
- Run the lamp alignment / peak search.
- Check the current energy level for the HCL.
- Clean the optical path and re-check; replace the lamp if still low.
- Confirm the atomizer is free of contamination.
- Re-verify with an element check standard.
Symptom: Flame instability
- Clean the nebuliser and the burner slot.
- Confirm the fuel and oxidant flows per the method.
- Check for a gas-supply or gas-control fault.
- Re-light and observe stability.
- Re-run a standard to confirm sensitivity.
