DW-AA4530F Atomic Absorption Spectrophotometer

CHARACTERISTICS

1. Completely controlled by PC, canflexibly 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 thehollow 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 andthe 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 thelifter

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

ADVANCED GRAPHITE FURNACE TEMPERA-TURE CONTROLLING TECHNOLOGY

The bringing in of PID technology can effectively overcome the influence on thetemperature rising process caused by the voltage fluctuation andthe 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 needof dynamic power of 380V

The maximum procedure heating capacity setting of20 levels can make a more convenient and easier testof different samples

Three grades adjustable gas flow can accustom to moreapplication needs

Can  timely  alarm  when  the  gas  and  water  is stopped and insufficient gas and water, can avoid the equipment damage and measuring error
