Double Beam DW-AA320N Atomic Absorption Spectrophotometer (1 Lamp Stand)

An atomic absorption spectrometer(AAS), also known as atomic absorption spectrophotometer, analyzes metal elements according to the effect of ground state atomic vapor on characteristic radiation absorption. It can determine trace or trace elements sensitively and reliably.

Optional Accoessories:

  • Graphite Furnace
  • Air Compressor
  • Printer
  • Burner Head
  • Software ( No computer )
  • Glass atomizer
  • Hydride Generator
  • Chilled water unit
  • Ventilating Hood ( 1.5 meters )

Features of DW-AA320N Atomic Absorption Spectrophotometer

  1. Build-in computer data processing and LCD display: stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp background correction, multi-linear and nonlinear curves fitting, various parameters, and working curves displayed in the screen and report printing, etc. It is equipped with an interface for externally linking PC.
  2. Stability: Double-beam system can automatically compensate for the light source drift and wavelength drift caused by the variation of temperature (with the function of eliminating the affection of wavelength drift on the baseline stability) and electronic circuit drift so as to reach good basic line stability.
  3. Quickly: The cathode lamp needs not to be pre-heated for a long time and the sample can be analyzed immediately. It is the preferred instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.
  4. High precision of measurement: The gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. A specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration
  5. High energy optical path: A total reflection system is adopted to eliminate the color differences in the 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 the double beam is enhanced.
  6. Long-life and anti-corrosive atomization system: The burner is made of a new type of titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
  7. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption, and hydride generation.
  8. 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.
  9. Complete set of accessories: to be supplied with the instrument and ready for use after they are purchased.
