Flame graphite furnace integrated atomic absorption spectrometer
High precision fully automated optical system
A large-area grating with a dispersion rate of 1800 lines per millimeter, a new self collimating monochromator, and all lenses are coated with quartz. The wide detection range and optical stability ensure the accuracy of analysis. The fully automatic lamp holder is equipped with an independent lamp power supply, which can be preheated separately
Polymer atomization chamber
Polymer material corrosion-resistant atomization chamber, acid and alkali resistant, including hydrofluoric acid, can achieve good sensitivity and stability in both organic and inorganic solutions
Titanium burner
Optional 50mm and 100mm burners, air-cooled premixed type, corrosion-resistant, high salt resistant, greatly improving flame efficiency and flame analysis accuracy.
Fully automated analysis
It can automatically complete safe ignition, extinguishing, and switching, with a reliable structure and low failure rate, thus ensuring the sensitivity and reproducibility of the flame method. The light source lamp position platform automatically switches, and high-performance hollow cathode lamps can be directly used to improve the sensitivity of flame analysis. The power supply parameters and beam position are automatically adjusted, and the wavelength scanning and peak finding are fully automatic
Graphite furnace temperature control
Dual temperature control of internal and external air, with a 20th order linear or nonlinear heating to ensure good sensitivity of the tested element; Enriched and concentrated in the furnace for 20 times, the temperature of the inner wall of the graphite tube can be monitored by longitudinal light control, and the highest temperature can be raised to 3000 ℃ C/s
High tech indicators
The element testing sensitivity of AA-1800 atomic absorption spectrometer has reached the advanced level in the industry, with a sensitivity of ≤ 0.015 μ g/mL/1%; Baseline drift less than 0.003Abs/30m, stability better than 0.005Abs/4h
Background correction system
The use of deuterium hollow cathode lamp and self absorbing buckle background for background correction eliminates the interference of molecular absorption during low content determination, reduces the emission noise of the gas lamp, prolongs its service life, and has good stability. When the background signal of the tritium lamp is 1A, the background deduction ability is greater than 50 times
Intelligent analysis
Very intelligent and user-friendly design, automatic switching between flames and graphite furnace atomizers, automatic optimization of graphite furnace atomizers, automatic setting and adjustment of flame height, automatic ignition, automatic optimization of horizontal position, and system automatic setting of gas flow rate. In case of power outage, misoperation, leakage, etc., the system will automatically activate the safety protection function
Automatic sampler
Integrated design with graphite furnace, using high-precision injectors, capable of feeding a minimum of 0.5u sample, with intelligent online dilution and concentration functions
