Anti-corrosive AAS Atomic Absorption Spectrophotometer
with Spectrum bandwidth 0.2nm, 0.4nm, 0.7nm, 1.4nm, 2.4nm, 5.0nm
Features
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 screen and report printing, etc. It is equipped with interface for externally linking PC.
2. 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.
3. Quickly: The cathode lamp needs not be pre-heated for long time and sample can be analyzedimmediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds ofelements and fast analysis of samples.
4. High precision of measurement: Gas path system is equipped with precision pressurestabilizing and current stabilizing devices to reach stable flame and low noise. Speciallydesigned fine light beam passes through the flame to ensure a high precision analyticaltest and low
characteristic concentration
5. High energy optical path: A total reflection system is adopted to eliminate color difference infull range. By means of chemical conversion, a round light spot of the light source becomes along light spot, which enters into the slit. Therefore the light flux of double beam is enhanced.
6. 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 withoutwater-cooling.
7. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphitefurnace atomic absorption and hydride generation.
8. Safe and reliable gas path system: Special devices of quick gas conversion and safetyprotection can be used to analyze air-acetylene flame as well as nitrous oxide-acetylene flameand 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 arepurchased.
