Single Beam 185-910nm AAS Atomic Absorption Spectroscopy for Mining
Metal Analysis
Introduction of Atomic Absorption Spectrophotometer
Atomic absorption spectrometry (AAS) is an easy, high-throughput,
and inexpensive technology used primarily to analyze elements in
solution. As such, AAS is used in food and beverage, water,
clinical research, and pharmaceutical analysis. It is also used in
mining operations to determine, for instance, the percentage of
precious metal in ores.
