Description :

　　LH-AA9626 Atomic Absorption Spectrophotometer (Single Flame)Features

　　1. Six lamp position light source, automatic switching of lamp positions, searching for element lamp positions;

　　2. Automatically adjust negative high voltage and constant current, with an average current between 3mA-5mA, to prolong the service life of hollow cathode lamps;

　　3. Total reflection optical system, eliminating chromatic aberration and improving optical efficiency;

　　4. Imported components improve instrument performance: imported original photomultiplier tubes, imported original 1800 line gratings;

　　5. Baseline stability ≤ 0.003A/30min, low noise, high sensitivity, good repeatability, ensuring the operation status of the instrument;

　　6. The use of Wu's high-efficiency glass atomizer significantly improves the sensitivity, detection limit, and stability of atomic absorption;

　　7.60 times or more deuterium lamp background correction capability (1Abs);

　　8. Titanium alloy combustion head, effectively preventing acid gas corrosion;

　　9. The single flame atomic absorption spectrometer can measure more than 20 elements such as ppm chromium, nickel, lead, zinc, etc. After selecting a graphite furnace, it can detect more than 20 elements such as ppb level silver, aluminum, arsenic, etc
