4530 Atomic Absorption Spectrophotometer

Features

1. Using PC control, the atomic absorptionspectrophotometer can flexibly select the flame and graphitefurnace atomizer.
2. The integratedfloated optical platform design can obviously improve the optical system shockresistance and can keep stable though use the optical signal for a long term.
3. The eight lightstands can be changed automatically and preheat the eight element lights in themeantime as well as optimize the working condition of the hollow cathode lamp.
4. Due to the bestheight of the flame burner, the atomic absorption spectrophotometer canautomatically set the front and rear positions.
5. It offers fullyautomated wavelength scanning and peak searching.
6. The atomicabsorption spectrophotometer can support the function of warning and automaticsafety protection towards the wrong burner, leakage of the gas, under voltageof air and the abnormal flameout.
7. It offers a deuterium lamp and self-absorption backgroundregulation.
8. It features data processing: super strong database,possesses more than 500 data self-storage and cut-off storage function, canstore the analyzed result with the form of EXCEL and the testing method and theresult can be randomly called.
9. The atomic absorption spectrophotometer uses twomeasuring methods, including the flame absorption method and emission method.
10. It offers result printing: parameter printing, dataresult printing and diagram printing.

Advantages
1. Complete automatic controlling system

2. With the help ofthe 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

3. Advanced graphitefurnace temperature controlling technology
Bringing in PID technology can effectively overcome theinfluence on the temperature rising process caused by the voltage fluctuationand the resistance change to make a more accurate controlling process. Thecombination of the 3ms/time fast sampling technique can make more accurate andreliable testing data.
The fast heating capacity can further improve theflexibility of the elements.
The ordinary power source of 220V can be used without needof dynamic power of 380V.
The maximum procedure heating capacity setting of 20 levelscan make a more convenient and easier test of different samples.
Three grades adjustable gas flow can accustom to moreapplication needs.
A timely alarm is sounded when the gas and water is stopped and insufficientgas and water. This can avoid the equipment damage and measuring error

4. Safe, reliable andconvenient flame system
EPC can control the flow of acetylene(C2H2) more accurately and this type of system can be easily operated.
An eefficient atomization system enables a highersensitivity.
The whole operation system has a high security as the firesafety system can sound whenever the electricity is cut off, abnormal flameoccurs, a lack of pressure happens or the burner does not match well. It willautomatically turn off the gas, prohibit tempering. It keeps the operationpeople and equipment from harm and damage.

5. Multi-functionalsoftware workstation
A workstation that is supported WINDOWS XP/2000/NT.
The rich menu brings great convenience to the use ofcustomer.
Convenient conversion between different menus makes theoperation easier.
Various analytical correction methods provide the users morechoices.
Basic default parameter settings enable even beginners tomanage the normal operation.
Flexible storage, editing and printing methods give the userthe largest support
