Product Description

Atomic absorption spectrophotometer

Characteristics A
Buildin 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 zeroadjusting, dlamp and background, multilinear 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.
Good basic line stability: Doublebeam 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 preheated 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.
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
Longlife and anticorrosive atomization system: The burner is made of new type titanium alloys, anticorrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
Multifunctional analysis mode: For methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.
Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used toanalyze air-acetylene flame .
Complete set of accessories: To be supplied with the instrument and ready for use after they are purchased.

Characteristics B
Lightsource system: Hollow cathode lamp power supply: with adjustable current D  Lamppower supply:with fixed current
Optical system: Double beam total refection system, CT type monochromator Flashing wavelength: 250nm
Flame atomization system: Interchangeable titanium alloy burner of 10cm and 5cm slits. Gas path is equipped with pressure indication, high precision voltage stabilizing flow adjustment, fast conversion of air and nitrous oxide, gas supply cut off, power cut off, prevention of flashback and logic interlock protection devices.
Signal processing: Absorptance, concentration, emission and emission concentration; 
Standard curves: linear regression, curve fitting and multipoint standard calibration. Average value, standard deviation, relative standard deviation and correlation coefficient can be worked out. Standard curves, atomic absorption peak diagram, spectrum outline sketch, data as well as instrument parameters list and analytical reports can be displayed and printed out.
Accessory:Main accessories supplied with the instrument: Several decades of accessories including air compressor, one piece of Cu hollow cathode lamp. Gas external pipe, acetylene cylinder pressure-reducing valve and water knockout gas filter.

Optional accessories:
GA3202 HGA graphite furnace system: Used to conduct trace and ultratrace analysis with an absolute sensitivity of 10-10-10-12 gram.
5cm long-life titanium burner: The necessary accessory for nitrous oxide-acetylene flame analysis.
Hydride generator (Totally automatic): Making the characteristic concentration of As, Se,Sb, Bi, Pb, Sn, Te, Ge, In, Tl,Cd and Zn lower than ppb level with cold atomic mercury measurement method.
Hollow cathode lamp: All specifications are available.
Graphite tube: All specifications are available.
