Main features


High precision automatic optical system
1800 / mm reticle (dispersion rate) large area grating monochromator, a new type self collimation, all lenses are quartz coating, the detection range and the stability of optical broad to ensure the precision of analysis. Automatic 8 socket configuration 8 independent lamp power supply, can be respectively preheating

Polymer spray chamber
Polymer materials corrosion spray chamber, acid and alkali resistance, includinghydrofluoric acid, either organic or inorganic solution can be the highest sensitivity andstability

Titanium burner
Titanium burner, the optional 50mm and 100mm burner, air cooling pre mixed type,corrosion resistant, resistant to high salt, greatly improve the analysis efficiency andaccuracy of the flame

Automatic analysis
It can automatically accomplish safety ignition, extinction and switching, reliable structure,low fault rate, thus ensuring the sensitivity and reproducibility of the flame method.
The light source system six lamp automatic conversion, can be directly used high performance hollow cathode lamp, improve the sensitivity analysis of the flame, the automatic adjustment of the power supply parameters and the beam position, automaticwavelength scanning and searching peak


Software function
High intelligent software, powerful function, friendly interface English operation.Automatic instruments and additional control, flame, graphite furnace operating mode can be switched automatically, automatic optimization, automatic dilution; mouse operation, automatic setup menu data and correction method

Graphite furnace temperature control
Gas dual temperature control inside and outside, 20 order linear or nonlinear heating, to ensure that the measured elements has the highest sensitivity; furnaceenriched up to 20 times, the longitudinal optically monitoring the graphite tube wall temperature, maximum temperature to 3000 degrees centigrade.

High technology index
AA-1800 atomic absorption spectrophotometer elements testsensitivity meet international best level,sensitivity of less than or equal to0.015μg/mL/1%; baseline drift is less than 0.003Abs/30m, the stability is better than 0.005Abs/4h

Background correction system
Using deuterium hollow cathode lamp advanced and self absorption background deduction of background correction, to eliminate the interference of molecular absorption of low content determination, reducing the noise emission of deuterium lampand prolongs the service life, has excellent stability. Deuterium lamp background signalfor 1A,
