4730FG atomic absorption spectrophotometer characteristic: 1. The flame and graphite furnace atomizers are integrated on the same host, and the software automatically switches between the flame and graphite furnace atomizers without the need to readjust the position of the atomizers. 2. The 8-lamp bracket automatically rotates, and the 8-lamp positions are fully automatic, stable, and reliable for switching and preheating, automatically optimizing the working conditions of the hollow cathode lamp. 3. Position adjustment: The optimal height and front and rear positions of the flame burner are automatically set. 4. Fully automatic wavelength scanning and peak searching, self absorbing background subtraction method 5. When the background signal is 1A, the background correction capability of D2 is greater than 60 times 6. The water seal tank and liquid level sensor are integrated below the atomization chamber, making it more convenient to use 7. Safety system: Automatically cuts off gas in case of insufficient pressure, power interruption, flameout, or mismatched combustion head. 8. Advanced and precise temperature control technology for graphite furnaces. 9. Equipped with a high-definition camera as standard, the automatic adjustment of the injection needle position is more convenient, and the entire process of graphite furnace injection is visualized. 10. The total reflection optical system uses two non spherical optical elements to strictly correct astigmatism, effectively improving the energy at the entrance slit of the monochromator. Technical parameters: Instrument type: Flame graphite furnace Monochromatic component: concave grating Optical system: single beam Detector class: photomultiplier tube Background technology: deuterium lamp+self absorbing background clip Repeatability (RSD): Flame method ≤ 0.45% (Cu); Graphite furnace method ≤ 2% (Cd) Detection limit: Flame method: 0.003 μ g/mL (Cu); Graphite furnace method: Cd ≤ 1.0pg Baseline stability: ≤ 0.002A/15min (static Cu spectral line)
