주요 특징
High precision fully automated optical system
A large area grating with a dispersion rate of 1800 lines/mm, a new self-collimating monochromator, all lenses are quartz coated, a wide detection range and optical stability ensure the accuracy of the analysis. The automatic 6 lamp holder is equipped with 6 independent lamp power supplies, which can be preheated respectively.
Polymer atomizing chamber
Polymer material anti-corrosion atomization room, acid and alkali resistance, including hydrofluoric acid, whether organic or inorganic solution can get better sensitivity and stability;
Titanium burner
Titanium burner, optional 50mm and 100mm burner, air cooled premixed type, 내식성, high salt resistance, greatly improve the efficiency of flame and accuracy of flame analysis;
Fully automated analysis
It can automatically complete safe ignition, extinguishing and switching, reliable structure and low failure rate, thus ensuring the sensitivity and reproducibility of flame method.
Light source system six lamp platform automatic switching, can directly use high-performance hollow cathode lamp, improve the sensitivity of flame analysis, automatic adjustment of power supply parameters and beam position, automatic wavelength scanning and wave peak search;
Graphite furnace temperature control
Dual temperature control of inside and outside gas, 20 order linear or nonlinear temperature rise, to ensure that the element to be measured has a good sensitivity; The inner wall temperature of the graphite tube is monitored by longitudinal light control. The temperature can rise up to 3000℃/s.
High technical index
The element test sensitivity of AA-1800 atomic absorption spectrometer reached the advanced level of the industry, sensitivity ≤0.015μg/mL/1%; The baseline drift is less than 0.003Abs/30m and the stability is better than 0.005Abs/4h.
Background correction system
Deuterium hollow cathode lamp and self-absorption buckled background are used for background correction, which eliminates the interference of molecular absorption in low content determination, reduces the emission noise of deuterium lamp, prolongs the service life and has good stability. When the background signal of deuterium lamp is 1A, the background deducting ability is more than 50 타임스.
