AA320NAtomic Absorption Spectrophotometer
Features
1. Built-inComputer Data Processing and LCD display
It is reliable with the functions of integral holding, peak height and area, autozero adjusting, deuterium lamp and background, multi-linear and nonlinearcurves fitting, various parameters and working curves displayed in screen andreport printing, etc. The atomic absorption spectrophotometer is equipped withinterface for externally linking PC.
2. Goodbasic line stability
The double-beam system ofoptimized design can automatically compensate the light source drift andwavelength drift caused by the variation of temperature (with the function ofeliminating the affection of wavelength drift on the base line stability) andelectronic circuit drift. The cathode lamp does not need to be pre-heated for along time and the sample can be analyzed immediately. The atomic absorptionspectrophotometer is the preferable instrument chosen by users to conduct afast analysis of samples.
3. OpticalPath of High Energy
A total reflection system is used to eliminate color difference in full range.By means of chemical conversion, a round light spot of the light source becomesa long light spot which enters into the slit, enhancing the light flux ofdouble beam.
4. Long-lifeand Anti-corrosive Atomization System
The burner of the atomic absorption spectrophotometer is made of new typetitanium alloys, anti-corrosive and fast thermal equilibrium. It meets therequirement of measurement sensitivity without water-cooling.
5. Multi-functionalAnalysis Mode
The atomic absorption spectrophotometer can supportmethods of flame absorption, flame emission, graphite furnace atomic absorptionand hydride generation.
6. Safeand Reliable Gas Path System
Special devices of quick gas conversion and safety protection can be used toanalyze air-acetylene flame and extend the analytic elements to reach more than60.
