AAS/Atomic Absorption Spectrophotometer
AA4530
Features:
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 flame out.
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 GRAPHITEFURNACE TEMPERA- TURE CONTROLLING TECHNOLOGY
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 makemore accurate controlling process. The combination of the 3ms/time fast sampling technique can make more accurate and reliable testing data
The fast heating capacity can improve the flexibility of the elements further
Use the ordinary power source of 220V without
need of dynamic power of 380V
The maximum procedure heating capacity setting of 20 levels can make a more convenient and easier test of different samples
Three grades adjustable gas flow can accustom to more application needs
Can timely alarm when the gas and water is stopped and insufficient gas and water, can avoid the equipment damage and measuring error
SAFE, RELIABLE AND CONVENIENT FLAME SYSTEM:
EPC can control the flow of Acetylene (C2H2) more accurately and it is a kind of system which also can operate easily
Efficient atomization system enables a higher sensitivity
The whole operation system has a high security as the fire safety system can alarm whenever the electricity is cut off, abnormal flame occurs, a lack of pressure happens or the burner does not match well. And it will automatically turn off the gas, prohibit tempering. Thus it keeps the operation people and equipment from harm and damage.
MULTI-FUNCTIONAL SOFTWARE WORKSTATION
