The AELAB AA-7050 Series Atomic Absorption Spectrophotometer combines precision optical performance with advanced automation for elemental analysis across scientific, environmental, and industrial laboratories. Designed to measure more than 70 elements at both trace and macro concentrations, it provides reliable performance for metallurgy, petrochemical, and environmental applications.

 

⚙️ Design & Construction

The AA-7050 Series features a compact and stable optical bench with C-T grating mono-chromator and 1800 lines/mm diffraction grating for enhanced resolution. The instrument’s unique suspension design isolates the optical system from vibration and temperature variation. The integrated flame and graphite furnace atomizer is housed within a single enclosure, with automatic deuterium lamp background correction and high-stability power regulation.

 

🔬 Working Principle / Testing Method

The system operates on the principle of atomic absorption spectrometry. It quantifies elemental concentrations by measuring absorbance at element-specific wavelengths between 190 – 900 nm. Automated flame and graphite switching allows continuous analysis without optical realignment. A deuterium lamp compensates for molecular background absorption, while multi-step graphite temperature control achieves atomization up to 3000 °C for trace-level detection.

 

💡 Key Advantages

  • Automatic wavelength positioning and slit switching within 40 seconds
  • Automated flame height and lamp current optimization for best sensitivity
  • Deuterium lamp background correction and self-absorption reduction
  • Multi-element sequence analysis for up to 8 elements automatically
  • Graphite furnace camera system for real-time monitoring of atomization
  • Temperature correction programs extending graphite tube lifespan to >1000 firings
  • Under-pressure and over-heating protection for complete operator safety

 

🔗 Connectivity & Integration

The AA-7050 Series supports full PC operation via dedicated AELAB software, with USB data export and GLP-compliant reporting. Calibration curves, spectra, and analysis logs can be automatically saved and printed. Optional integration modules include the HG-01 Hydride Generator, AS-600 Auto-Sampler, and EW-320AC Air Compressor.
