AA-7090 Atomic Absorption Spectrophotometer

Description

The imported horizontal heating graphite furnace adopts the dual background correction mode of longitudinal AC Zeeman and deuterium lamp to meet the analysis needs of different users; 

the AC Zeeman background correction magnetic field is continuously adjustable in the range of 0.6T-1.1T to reduce the influence of the inversion effect on the analytical sensitivity; 

the graphite furnace visual system can locate the injection needle, observe the state of the sample in the graphite tube and optimize the graphite furnace temperature program, etc.;

the graphite furnace energy-saving mode can improve the effective utilization rate of the protective gas, extend the gas use time and reduce the use cost; 

the graphite furnace has dual protective gas paths, which can extend the life of the graphite tube by controlling the inner gas path and the auxiliary gas path; 

8 lamp holders, with coded lamp function, can automatically identify the type of element lamp and record the life of the element lamp; the

software can realize the functions of element lamp selection, wavelength selection, slit selection, burner head height and flow setting, automatic ignition, atomizer switching, deuterium lamp path switching, graphite furnace power switch, etc.;

the deuterium lamp fine-tuning mechanism can adjust the deuterium lamp light to coincide with the element lamp light;

it is equipped with a laughing gas safety lock and related safety mechanisms, making the use of laughing gas-acetylene flame safer.
