Features
- High precision fully automatic
optical system
Large
area grate with 1800 lines/mm dispersion rate, novel self-collimating
monochromator, all lense are Shi Ying coated, wide detection range and optical
stability ensure that accuracy of analysis. Automatic 6 lamp holder equipped
with 6 independent lamp power supply, can respectively preheating.
- Polymer atomizing chamber
High-molecular
material anti-corrosion atomization chamber, acid and alkali resistant,
including hydrofluoric acid, whether organic or inorganic solution can get
better sensitivity and stability.
- Titanium burner
Titanium
burner, optional 50mm and 100mm burner, air cooling pre mixed type, corrosion
resistance, high salt resistance, greatly improve the efficiency of the flame
and flame analysis accuracy.
- Fully automated analysis
It can
automatically complete safe ignition, extinguishing and switching, with
reliable structure and low failure rate, thus ensuring the sensitivity and
repeatability of the flame method;The light source system automatically switches
the six-lamp-position platform, can directly use the high-performance hollow
cathode lamp, improves the sensitivity of flame analysis, automatically adjusts
the power supply parameters and the beam position, and
fully automatically scans and searches for the wave crest.
- Graphite furnace temperature
control
Double
temperature control of internal and external air, 20-order linear or nonlinear
temperature rise, to ensure that the elements to be tested have good sensitivity;
Enrichment and concentration were carried out for 20 times in the furnace. The
inner wall temperature of the graphite tube was monitored by longitudinal light
control, and the maximum temperature could be increased to 3000 C/s.
- High technology index
The
element test sensitivity of AA-1800 atomic absorption spectrometer reaches the
advanced level in the industry, with the sensitivity ≤0.015 µ g/mL/1%; Baseline
drift less than 0.003Abs/30m with better stability than 0.005Abs/4h.
- Background correction system
The
deuterium hollow cathode lamp and the self-absorption button background are
adopted for background correction, so that the interference of molecular
absorption in the determination of low content is eliminated, the emission
noise of the deuterium lamp is reduced, the service life is prolonged, and the
deuterium hollow cathode lamp has good stability. When the background signal of
deuterium lamp is 1A, the background subtraction ability is > 50 times.
- Intelligent analysis
Intelligence
is very strong, humanized design, flame and graphite furnace atomization device
automatic switching, graphite furnace atomization device automatic
optimization, automatic setting to adjust the flame height, automatic ignition,
automatic optimization of horizontal position, the system automatically set the
gas flow. In case of power outage, misoperation, acetylene leakage, etc., the
system will automatically start the safety protection function;
- Automatic sampler
Integrated
with graphite furnace, high-precision injector was used, and the minimum volume
of sample could be 0.5 µL. The intelligent online dilution and concentration
function was realized.
