Product Features

DW-AA4530F Atomic Absorption Spectrophotometer

 

CHARACTERISTICS
1. Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional).
2. Integrated floated optical platform design can obviously improve the optical system shock resistance and keep stable though use the optical signal for a long term.
3. Eight light stands can be changed automatically and preheat the eight lights meantime as well as optimize
the working condition of the hollow cathode lamp.
4. Position adjusting: the best height of the flame burner and can automatically set the front and rear positions.
5. Fully automated wavelength scanning and peak searching.
6. 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.
7. Deuterium lamp and self-absorption background regulation.
8. 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.
9. Measuring method: flame absorption method and emission method.
10.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
1. Selection of the element lamp
2. Up-down-front-rear adjustment of the lifter
3. Adjustment of the optical energy
4. Selection of the slit
5. Determination of wavelength scanning and peak searching
6.  Selection of the atomizer
7. Setting of the background deduction method
8.  Controlling of the gas flow
9. Automatic flaming and flaming out
10.Setting of the graphite furnace testing method

 

ADVANCED GRAPHITE FURNACE TEMPERA-TURE CONTROLLING TECHNOLOGY
1.The bringing in of PID technology can effectively overcome the influence on the temperature rising process caused by the voltage fluctuation and the resistance change to make more accurate controlling process. The combination of the 3ms/time fast sampling technique can make more accurate and reliable testing data
2.The fast heating capacity can improve the flexibility of the elements further
3.Use the ordinary power source of 220V without need of dynamic power of 380V
4.The maximum procedure heating capacity setting of 20 levels can make a more convenient and easier test of different samples
5.Three grades adjustable gas flow can accustom to more application needs
