Atomic Absorption Spectrometer
Atomic absorption spectrometry (AAS) is a single-element technique that measures the concentrations of elements. Air/acetylene or nitrous oxide/acetylene flame is used to generate ground-state atoms. The light emitted from a hollow cathode lamp, specific to the element measured, is passed through the flame and measured by a segmented solid-state detector. The sample of interest is aspirated into the flame, and if that metal is present in the sample, it will absorb some of the light, thus reducing its intensity. The change in intensity is directly related to the concentration of that element in the sample.
Instrument: Perkin Elmer AAnalyst 400 AA Spectrometer
Specs
- System: True dual beam, Echelle monochromator optics, and deuterium background correction.
- Detectors: High-efficiency segmented solid-state detector.
- Lamps: Hollow cathode lamps.
- Wavelength range: 189-900 nm.
Sample requirements
Detailed information should be given about the samples, such as the composition of the matrix, expected concentrations, and legally required concentration levels. If the sample is brought in solution, a blank solution should also be supplied with the sample.
