AA500 Atomic Absorption Spectrometer
Features:
Fully Automated
* The flame and graphite furnace is integrated into one instruments.The change over from one technique to another is carried out by simple key strokes within the software.
* The instruments have a motorised 8 hollow cathode lamp turret which allows the automatic positioning and optimization of each hollow cathode lamp by the software.
* The spectral bandwidth is automated and is available with choice of five slit sizes.
Advanced Graphite Furnace
* Horizontally heated platform graphite tube.The unique design of graphite furnace reduces the chemical
interference effects and memory effects by uniformly heating the graphite electrode.
* The computer controlled heating program all.Iows the users to select the best heating program for analysis.
* The optical temperature during the atomization stage ensures the rapid heating and rapid analysis.This helps to
extend the life of graphite tube and enhance the analytical accuracy.
