Atomic Absorption Spectrophotometer (AA320N)

Product Description

1. Build-in computer data processing and LCD: Adopting highly integrated micro digital circuit, which is stable and reliable with the functions ofintegral holding, peak height and area, auto zeroadjusting, deuterium lamp and background, multi-linear and nonlinear curves fitting, variousparameters and working curves displayed inscreen and report printing, etc. It is equipped withinterface for externally linking PC.
2. Good basic line stability: Double-beam system ofoptimized design can automatically compensatethe light source drift and wavelength drift causedby the variation of temperature (with the functionof 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. The cathode lamp needs not be pre-heated for long time and samplecan be analyzed immediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.
3. 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 highprecision analytical test and low characteristic concentration.
4. Optical path of high energy: 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.
5. 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.
6. Multi-functional analysis mode: For methods of flame absorption, flame emission, graphite furnace atomic absorption (AS-3020 automatic sample feeder can be installed) and hydride generation.
7. 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 asnitrous oxide-acetylene flame and extend the analytic elements to reach more than 60.
8. Complete set of accessories: To be supplied with theinstrument and ready for use after they are
Purchased.
