What does atomic absorption spectroscopy determine?
Atomic absorption spectrometry (AAS) detects elements in either liquid or solid samples through the application of characteristic wavelengths of electromagnetic radiation from a light source. Individual elements will absorb wavelengths differently, and these absorbances are measured against standards.
What type of result can AAS produce?
In clinical analysis, AAS can test for metals in whole blood, plasma, urine, saliva, brain and muscle tissue, the liver and hair. One example where atomic absorption spectroscopy can provide invaluable support is in measuring mercury levels in fish.
What metals can AAS detect?
Although AAS has been known to work as a measurement technique on some semi-metals, such as boron and silicon, metals work best. A major reason for this is that the atoms in metal elements are more easily readable.
How is iron determined by atomic absorption spectrophotometry?
DETERMINATION OF IRON BY ATOMIC ABSORPTION SPECTROPHOTOMETRY OBJECTIVES: 1. The student will analyze a sample of iron ore using atomic absorption spectrophotometry. 2. The student will use the calibration curve method of analysis. 3. The student will use the method of standard addition for this analysis.
