Product Description

High Accuracy Lab Graphite Furnace Atomic Absorption Spectrometer Aas Spectrophotometer 

Product Description

                                     AAS spectrometer flame atomic absorption spectrophotometer

Application:
1Buildin 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 zeroadjusting,lamp and background, multilinear 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.
2Good basic line stability: Doublebeam system of optimized design 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. 
3The cathode lamp needs not be preheated 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 
5Stabilizing 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
6Longlife and anticorrosive atomization system: The burner is made of new type titanium alloys, anticorrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
7Multifunctional 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 toanalyze air-acetylene flame .
9Complete set of accessories: To be supplied with the instrument and ready for use after they are purchased.
