Product Description Fully automatic atomic absorption spectrophotometer manufacturersAtomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions.The AA-4530F atomic absorption spectrophotometer is a single-beam instrument, equipped with a PC and dedicated programs for function controlling and data processing, for testing macro, micro and trace metal elements and semimetal elements.Feature: 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 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 printingComplete 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 errorSafe, 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.
