Features of DW-AA4530F Atomic Absorption Spectrophotometer

1.PC software control: can flexibly select the flame and graphite furnace atomizer (optional). All parameters of the instrument are set by computer software, and the program is automatically controlled.
2. Three working modes can be selected: absorbance (continuous integration signal, peak height/peak area integration signal), concentration straightness, and flame emission intensity. It has four signal modes: atomic absorption, background absorption, background deduction correction, and emission intensity.
3.1ntegrated floated optical platform design can obviously improve the optical system shock resistance and keep stable though use the optical signal for a long term.
4. Eight light stands can be changed automatically, with the functions of simultaneous preheating, automatic rotation switching, automatic ignition, and automatic optimization of the working conditions of hollow cathode lamps.
5. Position adjustment: The ideal height and front and rear position of the flame burner are automatically set.
6. Perfect safety interlock protection device: The system has an alarm safety protection function for incorrect connection of combustion head, gas leakage, air under pressure, abnormal flameout, etc.

7. 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.
8. Deuterium lamp and self-absorption background regulation. It has the functions of automatic wavelength scanning, automatic gain, background correction, automatic energy balance, and automatic peak search according to the peak search method.
9. 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.
10. Measuring method: flame absorption method and emission method.
11. Result printing: parameter printing, data result in printing, and diagram printing.

Advanced Graphite Furnace Temperature Controlling Technology

The bringing in of PTD technology can effectively overcome the influence on the temperature rising process caused by the voltage fluctuation and the resistance change to make a 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 the 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 of adjustable gas flow can accustom to more application needs
Can timely alarm when the gas and water are stopped and insufficient gas and water, can avoid 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 that also can operate easily
Efficient a Tomi zati on s ys tern enables a higher Sensitivity. The whole operating system has 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, prohibiting tempering. Thus it keeps the operation people and equipment from harm and damage.
