Characteristics:
? 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 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
Complete automatic controlling system:
With the help of the software, the following can be easily achieved
? Selection of the element lamp
? Up-down-front-rear adjustment of the lifter
? Adjustment of the optical energy
? Selection of the slit
? Determination of wavelength scanning and peak searching
? Selection of the atomizer
? Setting of the background deduction method
? Controlling of the gas flow
? Automatic flaming and flaming out
? Setting of the graphite furnace testing method
