Troubleshooting/Errors
146 Agilent 55B AA Spectrometer User’s Guide
9324 High emission: no peak
The instrument failed to peak at the selected emission wavelength. The
instrument Gain had been set to its lowest value but the signal was too high.
Possible causes include:
Emission Setup has not been performed.
Wrong wavelength selected.
Faulty PMT or related circuit.
The standard solution currently being aspirated has high concentration.
9329 No peak detected
The instrument failed to peak at the selected wavelength. The instrument Gain had
been raised to its highest value, but the hollow cathode lamp signal was too low.
Incorrect or noisy readings will result if the instrument is not optimized again.
Possible causes include:
Wrong hollow cathode lamp for this element.
Hollow cathode lamp misaligned, or the light path is blocked.
Faulty hollow cathode lamp.
The lamp current has been set to zero or too low.
The lamp position in the method is incorrect.
Suggested action:
Check that the optical light path is not obstructed in the sample compartment. Exit
then re-enter the Optimize page/window. This will cause the instrument to retry
the peaking.
9330 No peak detected
The instrument failed to peak at the selected wavelength. Another peak may be
near this wavelength. Incorrect or noisy readings will result if the instrument is not
optimized again.
Possible causes include:
Wrong hollow cathode lamp.
Wrong wavelength or method selected.
