Atomic Absorption Spectrophotometer

AAS-210,
Atomic Absorption Spectrophotometer
Features:
Innovated rich oxygen air-acetylene flame analysis
technique:
The patented flame analysis technique adopting rich
oxygen air-acetylene flame as the substitution for
nitrous oxide-acetylene flame for high temperature
element analyses, such as Ca, AI, Ba, W, Mo, Ti, V,
etc. Flame temperature is continuously adjustable
between 2300-2950°C, which makes it possible to
choose the best atomization temperature for
different elements. It features easy operation, low
analysis cost and wide flame AAS analytical range.
Rich oxygen flame will not pollute the environment
and is not harmful to human bodies. It's a breakthrough
in flame AAS analysis.
Integrated flame/graphite furnace atomization
system, changeable with flame emission burner:
● Automatically controlled changeover of the
 integrated flame and graphite furnace atomizer
 featuring easy operation and time saving
 eliminates human labor.
● A flame emission burner head can be installed to
 perform flame emission analysis to alkali metals as
 K, Na etc. 
Accurate fully automated control system:
● Automatic 6-lamp turret, automatic adjustment of
 lamp current and optimization of light beam
 position.
● Automatic wavelength scanning and peak picking.
● Automatic spectral bandwidth changing.
● Automatic changeover between flame and
 graphite furnace operation, automatic optimization
 of position parameters, automatic ignition and
 automatic gas flow setting.
Reliable fully automatic graphite furnace analysis:
● Adopting FUZZY-PID and dual curve mode
 light-controlled temperature control technique,
 temperature auto-correction technique, ensures
 fast heating, good temp. reproducibility & high
 analytical sensitivity. The temperature control
 accuracy is less than 1%.
● Graphite furnace with pneumatic control and
 pressure lock ensures constant pressure and
 reliable contact. 
● Multi-function autosampler features automatic standard
 sample preparation, automatic correction of sampling
 probe depth, automatic tracing and correction of liquid
 surface height in the sample vessel, with the sampling
 accuracy of 1% and reproducibility of 0.3%, realizing fully
 automation of graphite furnace analysis.
Perfect safety protection measures:
● Alarm and automatic protection to fuel gas leakage,
 abnormal flow, insufficient air pressure and abnormal
 flame extinction in flame system.
● Alarm and protection function to insufficient carrier gas
 and protective gas pressure, insufficient cooling water
 supply and over-heating in graphite furnace system.
Advanced and reliable electronic design:
● Adopting large-scale programmable logic array and
 Inter I2C bus technology.
● European type sockets and AMP adapters with high
 reliability to ensure long term reliability of the whole
 electronic system.
Easy and practical analysis software:
● Easy-to-use MS analysis software is made under Windows
 operating system, realizing fast parameter setting and
 optimization.
● Automatic sample dilution, automatic curve fitting,
 automatic sensitivity correction.
● Automatic calculation of sample concentration
 (content), mean value, standard deviation and relative
 standard deviation calculation.
● Multi-elements determination in sequence to the same
 sample.
● Measured data and final results can be printed out and
 edited in Excel format.
