Competitive Advantage:

?

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 6 socket configuration six 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.
