Each Atomic Aborption that we sell undergoes a thorough check and refurbishment process. This process is defined in six categories; Safety, Gas handling, Optics, Electronics, Mechanisms, & Analytical performance. Some of the details are listed below to give a taste of what is involved. This is by no means an exhaustive list.
Safety
- Change all O-rings and seals in the nebuliser, nebuliser block, spray chamber and burner.
- Check that all interlocks and micro switches function properly.
Gas Handling
- Inspect the spray chamber and its gas connections for leaks.
- Inspect all gas hoses for wear. Leak check all fittings both inside and outside the instrument.
- Check that acetone has not entered the instrument gas manifold.
Optics
- Check that external optical surfaces are clean.
- Using wavelength scan, check that the instrument will calibrate on specific spectral lines.
- Record wavelength accuracy and gain settings. Check D2 performance.
Electronics
- Check all diagnostic LEDs for correct display of instrument function.
- Check power supply voltages, in-built diagnostics, cables, and circuit boards.
Mechanisms
- Exercise solenoids and all motor drives over the full range.
- Check burner adjuster controls.
Analytical Performance
- Run real standard solutions with flame, optimise and report performance.
