China Bnaas-B320 Lab Atomic Absorption Spectrophotometer

Features:

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 compen

sate 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 prefera

ble 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 flflame and low noise.

Specially designed fine light beam passes through the flflame

to ensure a high precision analytical test and low characteris

tic concentration

5.High energy optical path: A total reflflection system is adopt

ed 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 flflux 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 flflame

absorption, flflame emission, graphite furnace atomic absorp

tion 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 flflame as well as nitrous oxide-acetylene flflame

and extend the analytic elements to reach more than 60.

9.Complete set of accessories: to be supplied with the instru

ment and ready for use after they are purchased
