Atomic Absorption Spectroscopy (AAS)

Atomic Absorption Spectroscopy (AAS) determines the presence of metals 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.

Atomic Absorption methods measure the amount of energy (in the form of photons of light, and thus a change in the wavelength) absorbed by the sample.  Specifically, a detector measures the wavelengths of light transmitted by the sample (the “after” wavelengths), and compares them to the wavelengths, which originally passed through the sample (the “before” wavelengths). A signal processor then integrates the changes in wavelength, which appear in the readout as peaks of energy absorption at discrete wavelengths.
