chemical analysis methods

Chemical analysis methods are techniques used to identify and quantify substances in a sample. Common methods include: 1. **Spectroscopy**: Analyzing how light interacts with a substance to determine its composition. 2. **Chromatography**: Separating components of a mixture to identify them individually. 3. **Mass Spectrometry**: Measuring the mass of molecules to identify their structure and composition. 4. **Titration**: Adding a solution of known concentration to determine the concentration of an unknown substance. These methods are crucial in fields like medicine, environmental science, and food safety, helping ensure safety and quality in various products and processes.
