The AA320N Atomic Absorption spectrophotometer by Labtech is a superior lab item that delivers accurate and dependable analysis. The product is great for found in analytical laboratories and commercial settings where elemental analysis is essential.

Among the key options that come with all the AA320N Atomic Absorption spectrophotometer is its power to evaluate numerous elements. This is authorized by the double atomizer that can switch between graphite and flame furnace atomization modes. The flame mode can be used for low-level analysis of elements, whilst the graphite furnace mode can be utilized for greater examples of analysis. This double system enables the accuracy and precision of the analysis outcomes.

The AA320N Atomic Absorption spectrophotometer is also easy to use, with an intuitive interface, enabling operators to easily and quickly input analysis parameters. The tool even offers a big example which can accommodate numerous examples, reducing the necessity for regular test modifications.

Another important function of this is its low detection limitations. The tool features a detection selection of 0.1 to 200 ppm, making it ideal for trace screening element and ecological analysis. It features high powerful range, enabling simultaneous analysis of both high and low-level elements.

The tool is robust and durable, with a top-notch optical system that minimizes interference from background noise. The AA320N Atomic Absorption spectrophotometer is full of security features, including automated shut-off in case of any system mistakes or energy outages

Product Description

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 analyzed immediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples

4, 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 high precision analytical test and low characteristic concentration.

5, High energy optical path, 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

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 without water-cooling

7, Multi-functional analysis mode, for methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation

8, Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame
