6810S AA atomic absorption spectrophotometer 

Introduction of instrument

6810S AA atomic absorption spectrophotometer is a combination of graphite furnace with automatic sampler for a module, solved the switch automatic sampler regulating and light path in the process of calibration problems. The hundreds of laboratory tested graphite furnace system has a very high cost performance. Can be used with flame atomic absorption spectrometer, from a high concentration of PPM level to level trace amounts of PPT can analysis; Atomization device without having to switch, which greatly simplifies the operation.
The innovation of graphite furnace visual system
Domestic initiative of multimedia graphite furnace visual system can visually monitor dry inside the graphite tube, ashing burn the sample liquid in the process of dynamic evolution, easily observe automatic sampler capillary injector needle into the graphite tube in the best position and depth, and platform in graphite tube insertion position, ensure the analysis accuracy and life of the graphite tube, and is the perfect training tool. 
Automatic gas control
Using two way outside of  tube and tube gas control, respectively, in the process of analysis outside keep ventilation pipe, gas pipe in the stage of atomization gas, effective protection of graphite tube, the limit to extend its life, and can obtain high sensitivity analysis. 


Optical stability
Integration platform for the suspension shock absorber optical design, optical system aseismic ability enhancement, caused by changes in temperature to reduce the influence of mechanical deformation of the optical system, even if the long-term use of optical signals can still remain stable. 
security
1 Insufficient pressure gas alarm and automatically stop heating. 
2 Cooling water shortage alarm, and automatically stop heating. 
3 Temperature overheat alarm and automatically stop heating. 
Graphite furnace temperature control technology

The introduction of the PID technology effectively overcome the influence of voltage fluctuation of temperature makes every stage can accurately control temperature control process, the change of the external power supply for almost had no effect on sensitivity and repeatability, measurement repeatability.
