AA-7050 Atomic Absorption Spectrophotometer

The upgraded product of the nationally recognized quality instrument AA-7020, this fully functional atomic absorption spectrophotometer features both optical temperature control and power temperature control heating modes. Equipped with a graphite furnace visualization system, it assists users in positioning the injection needle, observing sample conditions within the graphite tube, and optimizing graphite furnace temperature programs. Additionally, it incorporates a gas-saving mode for the graphite furnace, enhancing the effective utilization of protective gas.

   8-lamp automatic turret; 

    Automatic burner head lift with automatic flame height adjustment;

    Power and optical temperature control with heating rates up to 3000°C/s;

    High instrument sensitivity: absorbance of 5μg/ml Cu > 1.0A; low detection limit down to 0.003μg/ml; high precision with RSD up to 0.45%;

    Graphite furnace visualization system simplifies method development for the graphite furnace; 

    The entire optical system of the AA-7050 is mounted on a floating optical base, offering excellent resistance to vibration, temperature drift, and interference.

    The AA-7050 deuterium lamp spot adjustment mechanism optimizes the deuterium lamp position, maximizing the concentricity between the deuterium lamp spot and the element lamp spot for more accurate background correction.

    Dual internal gas paths in the graphite furnace add an auxiliary gas flow in addition to the protective gas, aiding sample ashing for improved results; 

    Intelligent frequency conversion: the software automatically identifies the power supply frequency and matches operation to that frequency; 

    Multi-element analysis capability, combined with the AS-600 autosampler, enables automated determination of multiple elements. 

    Burner head: 10cm slot length, all-titanium material, resistant to high salt and corrosion
