Atomic Absorption Spectrophotometer
Atomic absorption spectrometry (AAS) is a simple, and low-cost technique for analyzing elements in solution. It is employed in food and beverage analysis, water analysis, medical trials, and pharmaceutical evaluation. It can be used in mining activities to calculate the proportion of valuable metal in ores.
Sample Preparation:
Sample preparation involves transforming a liquid or solid specimen into such a form that the equipment can analyze for constituents. In the case of flame AAS, this includes atomizing the specimen, which results in a fine fog dispersion. This mist is then passed through a flame to break any residual molecular bonds. This is denoted as atomization. The liquid sample is injected directly into the cuvette in graphite furnace AAS, where it is converted into a thin mist.
Applications:
- Trace element detection in industrial effluent sources
- Steel or other metallic alloy's additive and
- Moderate contamination detection
- Metal concentrations in solution in a quantifiable form
