AAS8516 Flame Graphite Furnace Integrated Atomic Absorption Spectrometer

Introduction
The flame graphite furnace integrated atomic absorption spectrometer is used to determine the content of major,trace,and semi metallic elements in various substances.This machine adopts a PC and Chinese interface operation software,making the instrument operation simple and intuitive.By applying advanced electronic circuit systems and USB3.0 communication control, the instrument has achieved automatic adjustment of functions such as wavelength scanning,peak finding and positioning,spectral passband width,rotating element lamp holder,atomizer height and position,gas flow rate,lamp current,and negative high voltage of photomultiplier tubes.The instrument stores reference conditions for the analysis operation of all measured elements in various analysis methods.Users can modify the operating conditions as needed,

Features
C-T monochromator
Adopting a 1800 line/mm,shining wavelength 230nm grating splitting system.
Eight Element Light Tower
Working with one lamp,up to seven lamps can be preheated,saving time for changing lamps and preheating,making element measurement faster and more convenient.
USB3.0 communication method
The industry is the first to adopt a3.0 communication interface,which improves communication speed and is compatible with the latest computer Windows 10 system.
Background correction system
Dual switching and background subtraction between elemental and deuterium lamps,with two background correction modes deuterium lamp and self absorption.When the background signal is 1A,the background subtraction ability is more than 60 times.
Graphite Furnace System
Integration
The graphite furnace power supply and atomic absorption host are located in one instrument,which shortens the cable length, reduces the electromagnetic interference of the graphite furnace power supply to the outside world,and improves the heating efficiency of the graphite tube.
Graphite furnace has high temperature control accuracy and fast heating speed
By using high-power transformers,micro resistance cables,and light controlled heating methods,combined with software and hardware temperature correction systems,the temperature control accuracy in the high temperature section can reach±1%.
More safety measures to make sample analysis safer and more reliable
1)Cooling water flow monitoring
2)Carrier gas pressure alarm monitoring
3)Graphite tube temperature alarm monitoring
4)Graphite furnace temperature alarm monitoring
Automatic carrier gas flow control
The internal and external gases of the graphite furnace are automatically controlled by the computer according to the software heating process.
150 bit rotary graphite furnace automatic sampler
The polar coordinate turntable graphite furnace automatic sampler can achieve a common automatic sampler for flame and graphite furnace,with high positioning accuracy,stable and reliable operation,and convenient use and maintenance.
