AA-1800EL Atomic Absorption Spectrophotometer
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

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,
background correction ability > 60 times
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. In the
case of power failure, misoperation, acetylene leakage, the system
will automatically start the safetyprotection function
Automatic sampler
Integrative design of graphite furnace, using high precision
syringe, lowest in 0.5μl samples, with intelligent online dilution
and concentration function.
