Features of DW-AA320N Double Beam Atomic Absorption Spectrophotometer
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 screen and report printing, etc. It is equipped with interface for externally linking PC.
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.
Stability
Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift so as to reach a good basic line stability.
Long-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.
Safe and reliable gas path system
The gas circuit is equipped with pressure indication, high-precision pressure and flow regulation, gas cut-off, power failure, backfire prevention functions, and logic interlock protection devices.
Multi-functional analysis mode
For methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.
