Atomic Absorption Spectrophotometer

AAS AA320N

Common Features

1Build-in computer data processing and LCD display: stable and reliable with the functions of integral

holding, peakheight and area, auto zero adjusting, deuterium lamp background correction, 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.

2Stability: Double-beam system can automatically compensate the light source drift and wavelengthdrift

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.

3Quickly: The cathode lamp needs not be pre-heated for long time and sample can be analyzed

immediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.

4High 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.

5High energy optical path: 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.

6Long-life and anti-corrosive atomization system: The burner is made of new type titanium alloys,

anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.

7Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace

atomic absorption and hydride generation.

8Safe and reliable gas path system: Special devices of quick gas conversion and safety protection

can be used to analyze air-acetylene flame.

9Complete set of accessories: to be supplied with the instrument and ready for use after they are

purchased.
