Atomic absorption spectrophotometry allows the quantitative determination of the elemental concentration in solutions and solid matrices after decomposition of the sample. A solution is introduced in an atomization device (flame, graphite furnace or hydride system). Atoms in the ground state absorb light at a selected wavelength emitted by a hollow cathode lamp of the element of interest. The wavelength is a qualitative (element specific) parameter. The absorbed light is a measure for the concentration of the analyte in solution after calibration with standard solutions in the ppm-ppb range.
- Mono-element method for the quantitative determination of elemental concentrations in water, metals, alloys, polymers, coatings, rubbers, after complete dissolution/decomposition in suitable acids (e.g. microwave dissolution).
- Determination of toxic elements (e.g. Cr, As, Pb, Cd, …) in materials.
- Determination of the degree of siliconization on pharmaceutical rubbers using MiBK extraction solutions.
- Migration studies for pharmaceutical rubbers and packaging materials.
