            AA990 Atomic Spectrophotometer

            The AA900 Atomic Absorption Spectrometer is a versatile entry level instrument with a computer controlled Air/Acetylene flame for general laboratory requirements.

            Due to its high sensitivity and excellent performance, the instrument can be used for a wide range of applications including: 


            - Agriculture                  - Clinical                    -Environmental                   - Metal

            - Food                           - Mining                     -Geological                         - Petrochemical

            - Pharmaceutical           


            The versatile instrument is available in three configurations:

            AA990F    - Flame atomizer only

            AA990G    - Graphite furnace atomizer only 

            AA990FG  - Combined with flame and graphite furnace atomizer switch aromatically 


             Easy-to-use software

               - Automatic positioning and optimization of each hollow cathode lamp

               -  Control the fuel gas flows of the burner to optimize the best analytical.     Parameters

            -  Control the Czerny – Turner Monochromator

            -  Locate the wavelength and select the peak

            -  Control the electronic parameters of the photomultiplier tube detector and hollow cathode lamp current 

            -  Balance the absorbance and background energy

            -  Control the ignition of the flame

            -  Optimize the best heating program

             Integrated safety precautions for user protection by following:

               -  Burner Switch

               -  Flame Sensor

               -  Gas leak Sensor

               -  Drain Trap Sensor

               -  Power Loss Protection

               -  Circulation Water (graphite)

               -  Over Temperature Sensor (graphite)

             Precision accuracy with integrated correction system

             Life cycle value, best choice for less than 8 elements of analysis.
