                                              AA-1800EL Atomic Absorption Spectrophotometer                                       

Advantage of AA-1800EL    

Main features

1.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

2.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

3.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

4.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 8 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

5.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

6.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.

7.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

8.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,

background correction ability > 60 times

9.Intelligent analysis

Greart intelligence, humanized design, flame and graphite furnace atomizer automatic switching, automatic optimization of graphite furnace atomizer, automatically set the flame height adjustment, automatic ignition, automatic optimization of the horizontal position, system automatically sets the gas flow.

10.Automatic sampler

Integrative design of graphite furnace, using high precision syringe, lowest in 0.5μl samples, with intelligent online dilution and concentration function.
