Compositional analysis is a commonly used chemical analysis method used to determine the amounts of different components in a substance. The test items of component analysis can vary according to different samples and application fields. The following are some common component analysis test items:
1. Elemental analysis: used to determine the content of various elements in the sample, such as carbon, hydrogen, oxygen, nitrogen, etc. Commonly used methods include combustion analysis, spectral analysis, mass spectrometry, etc.
2. Gas analysis: used to detect components in gaseous samples, such as detecting oxygen, carbon dioxide, nitrogen, etc. in the atmosphere. Commonly used methods include gas chromatography, gas adsorption, etc.
3. Liquid phase analysis: used to detect components in liquid samples, such as dissolved oxygen and ion concentration in water. Commonly used methods include titration, electrochemical analysis, spectroscopic analysis, etc.
4. Solid phase analysis: used to detect the components in solid samples, such as the content of various elements in metal alloys. Commonly used methods include scanning electron microscopy (SEM), X-ray diffraction (XRD), etc.
5. Organic matter analysis: used to detect components in organic compounds, such as the content of active ingredients in drugs, the content of additives in food, etc. Commonly used methods include mass spectrometry, nuclear magnetic resonance (NMR), etc.
6. Radioactive material analysis: used to detect the content of radioactive elements in samples, often used in nuclear energy, environmental monitoring and other fields. Commonly used methods include radioactivity measurement, radiation counting, etc.
The above are only some common component analysis and testing items. There are many other items in practical applications. The specific selection depends on the sample type, testing purpose and requirements.
