Atomic Chemical Analysis Equipment 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.
