AAS Spectrophotometer
● Fully controlled by PC.
● The integrated floating optical platform design can significantly improve the shock resistance of the optical system, and the optical signal can remain stable even if the optical signal is used for a long time.
● The eight lamp holders can be replaced automatically, and the eight lamps are preheated at the same time to optimize the working conditions of the hollow cathode lamp.
● Position adjustment: The optimal height of the flame burner can be automatically set in front and rear positions.
● Fully automatic wavelength scanning and peak search.
● Complete safety interlock protection device: it has warning and automatic safety protection functions against misfire, gas leakage, air underpressure, and abnormal flameout.
● Deuterium lamp and self-absorption background adjustment.
● Data processing: Super powerful database, with more than 500 data self-storage and off-storage functions, analysis results can be stored in EXCEL format and test methods, and the results can be called arbitrarily.
● Measurement method: flame absorption method and emission method.
● Result printing: parameter printing, data result printing, chart printing.
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
● 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.
● 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 temper ing. Thus it keeps the operation people and equipment from harm and damage.
● A workstation that is supported WINDOWS7
● 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
