Basic Characteristics 

Atomic Absorption Spectrophotometer (AAS) is for determining the concentration of a particular metal (element) in a sample. AAS can be used to analyze the concentration of over 62 different metals.

  • Build-in computer data processing and LCD: adopting highly integrated micro digital circuit, which is stable and reliable with the functions of: integral holding, peak height and area, auto zero adjusting, deuterium lamp and background, multi-linear and nonlinear curves fitting, various parameters and working curves displayed in screen and report printing, etc. It is equipped with interface for externally linking PC.
  • Good basic line stability: Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability. There is no need to pre-heat the cathode lamp and sample can be analyzed immediately. It is the preferable instrument to conduct analysis of multiple kinds of elements and fast analysis of samples.
  • High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame, to ensure a high precision analytical test and low characteristic concentration.
  • Optical path of high energy: A total reflection system is adopted to eliminate color difference in full range. By means of chemical conversion, a round light spot of the light source becomes a long light spot, which enters into the slit. Therefore the light flux of double beam is enhanced.
  • Long-life and anti-corrosive atomization system: The burner is made of titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
  • Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption (with AS-3020 automatic sample feeder installed) and hydride generation.
  • Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach more than 60.
  • Complete set of accessories are supplied together with the instrument after the purchase of the instrument.
