火焰与石墨炉原子吸收光谱仪
If you only need one or a few metals — Pb, Cd, As in food, Cu and Zn in leach solutions, Na and K in brine — AAS is the economical route. This unit combines air–acetylene and N2O–acetylene flame with a graphite furnace reaching 3000 °C. Flame Cu limit is ≤ 0.01 mg/L; furnace Cd reaches ≤ 0.002 µg/L.
