Product Details

AAS4530 Atomic Absorption Spectrophotometer

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

Advanced graphite furnace temperature 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 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

A workstation that is supported WINDOWS XP/2000/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 storage, editing and printing methods give the user largest support
