The AELAB AA-7003 series Atomic Absorption Spectrophotometer is a powerful analytical instrument designed to identify and quantify elemental concentrations in a wide range of sample types. With the ability to analyze more than 70 elements at both standard and trace levels, this system offers unmatched precision and versatility across diverse applications including metallurgy, environmental testing, clinical diagnostics, agriculture, and food quality assurance.
Key Advantages :
Advanced Optical Performance
1- The AA-7003 incorporates a suspended optical system design that minimizes the influence of environmental temperature changes or vibrations, maintaining exceptional stability. (Patent No. ZL200620023296.X)
2- It is the first domestically developed AAS to utilize an 1800 lines/mm diffraction grating, delivering improved resolution and energy efficiency.
3- Its compact single-beam design supports strong signal output and extremely low detection limits—ideal for sensitive elements such as arsenic (As) and selenium (Se).
4- Equipped with deuterium and self-absorption background correction mechanisms to ensure precise calibration results.
5- A fully automated, computer-controlled six-lamp turret allows easy lamp selection, wavelength scanning and alignment, energy optimization, and more—all with just one click.
Compact and Integrated Architecture
1- The AA-7003 unifies the optical components, atomization unit, graphite furnace controller, and electronics into a single, space-efficient structure—marking it as one of the most compact AAS systems globally. (Patent No. ZL200620023298.9)
2- Enhanced power supply system extends the service life of the element-specific lamps.
3- Supports both manual and automatic transitions between flame and graphite furnace modes within 2 seconds—no need for optical realignment during switching. (Patent No. ZL200620023297.4)
Robust Safety Features
1- Built-in alarm systems protect against over-current in hollow cathode lamps.
2- Includes under-pressure detection for both combustion and shielding gases, gas leakage alarms, overheat protection for the graphite furnace, and flame monitoring for safe operation at all times.
