AA-7090 Atomic Absorption Spectrophotometer

Product Description

Model: AA-7090
Manufacturer: East-West Analysis EWAI

All-in-one unit for parallel installation of flame graphite furnaces with both deuterium lamps and Seemann background corrections
Magnetic field strength variable from 0.6T to 1.1T with 0.1T amplitude
With coded light function

Eight-lamp automatic turret, rapid automatic selection of elemental lamps, can truly realize the same project multi-element sequential determination
Wavelength setting: 180nm~900nm, computer controlled automatic wavelength fast scanning.
Original imported transverse heating graphite furnaceThe dual background correction modes of longitudinal AC Seeman and deuterium lamp are used to meet the analytical needs of different users;
Burning head: 10cm seam length, all titanium material, high salt and corrosion resistant;
The AC Seeman background correction magnetic field is continuously adjustable from 0.6T to 1.1T, reducing the influence of inversion effect on the analytical sensitivity;
The absorbance of 1 ppm copper was better than 0.2 Abs;
Temperature rise rate ≥2500℃/sec, adjustable;
Graphite Furnace Visualization SystemThe graphite furnace is used to optimize the temperature of the graphite furnace, to locate the injection needle, to observe the sample in the graphite tube and to optimize the graphite furnace temperature program;
Maximum working temperature of graphite furnace: 2700℃;
Graphite furnace gas-saving mode, improve the effective utilization of protective gas, extend the gas use time, reduce the cost of use;
Dual protection gas circuit for graphite furnace, prolonging the graphite tube life by controlling the inner gas circuit and auxiliary gas circuit;
Elemental lamp selection, wavelength selection, slit selection, combustion head height and flow rate setting, automatic ignition, atomizer switching, deuterium light path switching, graphite furnace power switch and other functions can be realized through software;
Deuterium lamp fine-tuning mechanism to adjust the deuterium lamp line to coincide with the elemental lamp line;
With laughing gas safety lock and related safety mechanismIt is safer to use with a laughing gas-acetylene flame.
