Model Released. Scientist using an atomic absorption (AA) spectrometer to analyse water samples. The results are displayed graphically by a computer. Atomic absorption spectrometry makes it possible to measure extremely small concentrations of about 40 different metals in a sample. Typical sensitivity might be one part of metal (lead,for example) in a million million parts,an accurate means of detecting pollution of water by heavy metals | |
