AA-7050 Atomic Absorption Spectrophotometer

Domestic good instrument AA-7020 upgrade product, full-function atomic absorption, with two heating modes of light-controlled heating and power heating, equipped with graphite furnace visualization system, which can better help users position the sample injection needle, observe the state of the sample in the graphite tube and optimize the graphite furnace temperature program, etc., and is equipped with graphite furnace gas saving mode, which improves the effective utilization rate of protective gas.

   8-lamp turret automatic;  

    Burner head automatic lifting, automatic adjustment of flame height;

    Power heating and light-controlled heating, heating rate up to 3000℃/s ;

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

    Graphite furnace visualization system, simplifies the difficulty of graphite furnace method development;  

    The entire optical system of AA-7050 is installed on a suspended optical base, with good anti-vibration, anti-temperature drift, and anti-interference advantages.

    AA-7050 deuterium lamp spot adjustment mechanism: can optimize deuterium lamp position, maximize the concentricity of deuterium lamp spot and element lamp spot, making background correction more accurate.

    Graphite furnace double internal gas path, adding an auxiliary gas path outside the protective gas to help sample ashing and obtain better results;  

    Intelligent frequency conversion, software can intelligently identify power supply frequency and automatically match to work at that frequency;  

    With multi-element analysis function, cooperate with AS-600 automatic sampler to realize automatic determination of multiple elements.  

    Burner head: 10cm slit length, full titanium material, high salt and corrosion resistance
