Atomic Absorption Spectrometry (AAS)

Atomic absorption spectrometry (AAS) is a fairly universal analytical method for determination of metallic elements when present in both trace and moderately high concentration level in liquid samples. Metals include Fe, Cu, Al, Pb, Ca, Zn, Cd and many more. It also measures the concentrations of metals in the samples. Typical concentrations range in the low mg/L range. This technique offers analysis of only one element at a time from liquid sample.
