Agilent 55B AA Atomic Absorption System Repair
The Agilent 55B AA is a flame atomic absorption spectrometer — a lab analytical instrument that measures the concentration of metal elements in a sample by aspirating it into a flame and measuring light absorption from an element-specific lamp. Its performance depends on the optical system, the detector, the burner/nebulizer, and the lamp circuitry, which is where service focuses.
June Company repairs and calibrates the Agilent 55B AA for analytical, environmental, and QC labs.
Common Agilent 55B AA problems we fix
- Optical-system realignment — drifted or misaligned optics reducing sensitivity, realigned for correct light throughput.
- Detector replacement — a degraded or failed detector (photomultiplier) reducing signal, replaced.
- Burner / nebulizer faults — clogged or misadjusted burner/nebulizer affecting the flame and sample uptake, serviced.
- Lamp-circuit faults — the hollow-cathode lamp drive not energizing correctly, repaired.
- Readings drift or won’t calibrate — recalibrated against reference standards.
FAQs
My 55B AA lost sensitivity — fixable? Yes. Optical, detector, and burner faults are repairable; we realign and service the system, then verify calibration so concentration measurements are accurate, with documented results.
Do you service the burner and nebulizer? Yes — they’re a core part of the service.
Every repair includes calibration verification and a 90-day parts-and-labor warranty. Email us or submit a service request.
