Product Details

Product Description

Product features: Characteristics
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 as well as nitrous oxide-acetylene flame
and extend the analytic elements to reach more than 60.
9.Complete set of accessories: to be supplied with the instrument and ready for use after they are purchased
