Graphite Furnace Atomic Absorption Spectroscopy (gfaas)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Graphite Furnace Atomic Absorption Spectroscopy (GFAAS) is a technique used for the quantitative analysis of trace elements in a sample by measuring the absorption of light by free atoms in a graphite furnace.
Key Features
- High sensitivity for trace elements
- Ability to analyze small sample volumes
- Wide range of elements can be analyzed
- Good reproducibility and precision
Pros
- High sensitivity allows for detection of trace elements at very low concentrations
- Small sample volumes required reduce sample preparation time and waste
- Ability to analyze a wide range of elements makes it versatile
Cons
- Expensive equipment and maintenance costs
- Requires specialized training to operate effectively
- Limited sample throughput compared to other techniques
