atomic absorption spectroscopy

[ə¦tä·mik əb¦sörp·shən ‚spek′träs·kə·pē]
(spectroscopy)
An instrumental technique for detecting concentrations of atoms to parts per million by measuring the amount of light absorbed by atoms or ions vaporized in a flame or an electrical furnace.

The TFHRC researchers began their approach to this analysis by removing the binder from the hot mix, using either combustion or solvent extraction; extracting the aggregate residue with acid; analyzing it for calcium either by atomic absorption spectroscopy or ion exchange chromatography; and back-calculating the lime content.
CCA-treated chips, OA-extracted chips, and remediated chips were analyzed for copper, chromium, and arsenic content by atomic absorption spectroscopy according to AWPA Al1-93 [2] (Table 1) and results were reported as oxide for each metal.
In more recent years, a few compounders have opted for XRF analysis as an alternative to traditional QA/QC techniques such as atomic absorption spectroscopy or specific-gravity tests.
Its laboratories employ multiple technologies, including Inductively Coupled Plasma (ICP), Atomic Absorption Spectroscopy (AAS) and UV/Visible Spectroscopy - applications, which require robust, high-performance instrumentation; such as PerkinElmer's Optima[TM] ICP-OES, AAnalyst(TM) atomic absorption systems and LAMBDA(TM) UV/Vis families.
