High-precision fully automated optical system:
Dispersion rate is 1800 lines/mm large area grating, new self-collimating monochromator, all lenses are quartz coated, wide detection range and optical stability ensure the accuracy of analysis. Fully automatic 6 lamp holders are equipped with 6 independent lamp power supplies, which can be preheated separately;
Polymer atomization chamber:
Polymer material anti-corrosion atomization chamber, acid and alkali resistant, including hydrofluoric acid, both organic and inorganic solutions can get good sensitivity and stability;
Titanium burner
Titanium burner, optional 50mm and 100mm burners, air-cooled premixed type, corrosion resistant, high salt resistant, greatly improve the efficiency of flame and the accuracy of flame analysis;
Fully automated analysis
Can automatically complete safe ignition, extinguishing and switching, reliable structure, low failure rate, thus ensuring the sensitivity and reproducibility of flame method. The six-position platform of the light source system automatically switches, and high-performance hollow cathode lamps can be used directly to improve the sensitivity of flame analysis, automatically adjust power supply parameters and beam position, and fully automatically scan wavelengths and find peaks;
Graphite furnace temperature control
Dual temperature control of internal and external gases, 20-order linear or nonlinear heating, to ensure that the elements to be measured have good sensitivity; the furnace is enriched and concentrated up to 20 times, and the longitudinal light control monitors the temperature of the inner wall of the graphite tube, which can be heated up to 3000℃/s;
High technical indicators
Sensitivity ≤0.015μg/mL/1%; baseline drift is less than 0.003Abs/30m, and stability is better than 0.005Abs/4h;
Background correction system
Use deuterium hollow cathode lamp and self-absorption background for background correction, eliminate the interference of molecular absorption during low-content determination, reduce the emission noise of deuterium lamp, extend the service life, and have good stability. When the background signal of the deuterium lamp is 1A, the background deduction ability is greater than 50 times;
