190nm ~ 900nm atomic absorption spectrophotometer for lab metal elements analysis

Brief introduction of AA320N:

1 Built-in computer data processing and liquid crystal display: the use of highly integrated computerized digital circuits, stable and reliable. With a variety of linear nonlinear curve fitting, the screen displays a variety of parameters and work curves, print reports and other functions, at the same time with an external personal computer interface.

2 Reliable baseline stability: Optimized design of the dual-beam system can compensate for drift of the light source, temperature changes caused by wavelength drift (with the effect of eliminating wavelength drift on the baseline stability of the function) and electronic circuit drift, therefore, with reliable baseline stability , The cathode lamp does not have to be preheated for immediate analysis of the sample, is the analysis of a variety of elements and rapid analysis of the sample users preferred instrument.

3 High precision of measurement: As the air system is equipped with precision regulator, steady flow device, flame stability, low noise, unique design of the fine beam from the flame through to ensure that the analysis of high precision, low characteristic concentration.

4 High-energy optical path: the use of total reflection optical system, full-band achromatic, and the light source of the circular spot through the optical transformation, a long spot into the slit, thereby enhancing the dual-beam luminous flux.

5 Long life corrosion-resistant atomic system: the combustion head with corrosion-resistant, rapid thermal balance of the new titanium alloy material, without water cooling can meet the requirements of stable measurement stability.

6 Multi-functional analysis: do the flame absorption, flame emission, graphite furnace atomic absorption (AS-3020 autosampler can be equipped with) and hydride generation method.

7 Safe and reliable air system: with fast gas conversion and safety protection device.

8 Complete accessories: random matching complete, after the purchase that can be used.

9 Optional data acquisition software and brand computer.
