Product Description
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
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
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 a tomi zati on s ys tem enables a higher sensitivity
The whole operation system has a high security as the fire safety system can alarm whenever the electrici- ty 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 temper ing. Thus it keeps the operation people and equipment from harm and damage.

MULTI-FUNCTIONAL SOFTWARE WORKSTATION
A w o r k s t a t i o n t h a t i s s u p p o r t e d W I N D OW S XP/20 00/NT
The rich menu brings great convenience to the use of customer
Convenient conversion between different menus makes the operation more easily
Various analytical correction methods provide the
users more choices
Basic default parameter settings enable even the beginners can do the normal operation
Flexible sto r age, e ditin g and p rin tin g m e th ods give the user largest support
