Description
Agilent 240Z AA Atomic Absorption System Repair
The Agilent 240Z AA Atomic Absorption System is an atomic absorption spectrometer – it atomises a sample in a flame or graphite furnace and measures how much light a hollow cathode lamp loses passing through it. The optical path and the atomisation source are the two things that determine whether the numbers mean anything.
The Agilent 240Z AA Atomic Absorption System is repaired at June Company by technicians who work on this class of instrument daily, for analytical laboratories, environmental testing facilities, metallurgical labs, and quality control departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Agilent 240Z AA Atomic Absorption System problems we fix
- Display, keypad or front-panel faults.
- Lamp energy low or unstable – hollow cathode lamps age, and falling energy degrades detection limits before it stops the instrument working.
- Burner or nebuliser blocked or misaligned – atomisation efficiency directly scales the absorbance reading.
- Graphite furnace tube or contact faults.
- Monochromator drive or wavelength accuracy errors.
- Photomultiplier or detector faults.
- Gas flow control and safety interlock faults.
- Baseline noise or poor reproducibility.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
FAQs
Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.
My detection limits have got worse but nothing is broken. Why? Usually lamp energy or nebuliser efficiency. Both degrade gradually, which raises detection limits long before anything fails outright.
