AA320N Atomic Absorption Spectrophotometer

AA320N Atomic Absorption Spectrophotometer

Short Description:

Brand:NANBEI

Model:AA320N

Built-in computer data processing and LCD display: stable and reliable, with integral hold, peak height, area, automatic zero adjustment, deuterium lamp background correction, multiple linear and nonlinear curve fitting, various parameters and working curve display and other functions. Screen and report printing, etc. It is equipped with an external connection to the PC interface.

Stability: The dual-beam system can automatically compensate for light source drift and wavelength drift caused by temperature changes (with the function of eliminating the effect of wavelength drift on baseline stability) and electronic circuit drift, so as to achieve good basic line stability.

Common features

★ Built-in computer data processing and LCD display: stable and reliable, with integral hold, peak height, area, automatic zero adjustment, deuterium lamp background correction, multiple linear and nonlinear curve fitting, various parameters and working curve display and other functions. Screen and report printing, etc. It is equipped with an external connection to the PC interface.
★ Stability: The dual-beam system can automatically compensate for light source drift and wavelength drift caused by temperature changes (with the function of eliminating the effect of wavelength drift on baseline stability) and electronic circuit drift, so as to achieve good basic line stability.
★ Fast: The cathode lamp does not need to be preheated for a long time, and the sample can be analyzed immediately. It is the first choice for users to analyze multiple elements and quickly analyze samples.
★ High measurement accuracy: The gas path system is equipped with a precise voltage stabilizing device, with stable flame and low noise. The specially designed thin beam passes through the flame to ensure high-precision analysis and testing and low characteristic concentration.
★ High-energy light path: The total reflection system is used to eliminate chromatic aberration in the entire range. Through chemical conversion, the circular spot of the light source becomes a long spot and enters the slit, so the flux of the double beam of light is enhanced.
★ Long-life, corrosion-resistant atomization system: The burner adopts a new type of titanium alloy material, which is corrosion-resistant, fast in heat balance, and can meet the measurement sensitivity requirements without water cooling.
★ Multifunctional analysis model: methods for flame absorption, flame emission, graphite furnace, atomic absorption and hydride generation.
★ Safe and reliable gas path system: using a special gas rapid switching device and safety protection cab, it can analyze air-acetylene flame and nitrous oxide-acetylene flame, and analyze more than 60 kinds of elements.
★ A full set of accessories: provided with the instrument, you can use it after purchase.
