uv vis double beam spectrophotometer

1. Build-in computer data processing and LCD: adopting highly integrated micro digital circuit,

which is stable and reliable with the functions of integral holding, peak height and area, auto zero

adjusting, deuterium lamp and background, 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. Good basic line stability: Double-beam system of optimized design 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. 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.

3. 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

4. Optical path of high energy: 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.

5. 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.

6. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace

atomic absorption and hydride generation.

7. 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.

8. Complete set of accessories: to be supplied with the instrument and ready for use after they are

purchased.
