Application
Nitric acid can be used for:
- Trace Metal Analysis: It is used in the digestion process for trace elements analysis, helping to identify potential contaminants such as heavy metals in the cigarette liquid samples).
- Sample Preparation: Employed in the digestion and dissolution of samples before analysis.
