Description

Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional)
Integrated floated optical platform design can obviously improve the optical system shock resistance and can keep stable though use the optical signal for a long term.
Eight light stands can be changed automatically and preheat the eight element lights meantime as well as optimize the working condition of the hollow cathode lamp
Position adjusting: the best height of the flame burner and can automatically set the front and rear positions
Fully automated wavelength scanning and peak searching
Complete safety chains protection equipment: the function of warning and automatic safety protection towards the wrong burner, leakage of the gas, under voltage of air and the abnormal flameout
Deuterium lamp and self-absorption background regulation
Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store the analyzed result with in the form of EXCEL and the testing method and the result can be randomly called
Measuring method: flame absorption method and emission method
Result printing: parameter printing, data result printing and diagram printing
