What are the main categories that make up the knowledge system of chemical analysis?
Generally, it can be divided into volumetric analysis and instrumental analysis. For a detailed classification, you can refer to analysis-related books, which provide thorough explanations.
Continuing from what the moderator yang*anghui from above wrote: Volume analysis: 1. Titrimetric analysis: acid-base titration, complexometric titration, redox titration, precipitation titration. 2. Gravimetric analysis. Instrumental analysis: 1. Spectral analysis: UV, AA, ICP, fluorescence. . . 2. Chromatographic analysis: gas phase, liquid phase. . . 3. Electrochemical analysis: potentiometry, coulometry, polarography. . .
When working in analysis, the questions people ask you usually fall into two categories: what is this thing, and what is its content? Therefore, it’s more convenient to organize knowledge into qualitative and quantitative categories for practical use.
Your question is too broad; it’s difficult for an ordinary person to answer it, as a lot of explanation would be needed to address it properly
Based on the analysis task, analysis object, measurement principle, and operation method, analysis methods can be divided into many types. Based on the analysis tasks: qualitative analysis, quantitative analysis, structural analysis. Based on the analysis methods: chemical analysis methods, instrumental analysis methods. As mentioned above: Chemical analysis methods include acid-base titration, complexometric titration, redox titration, and precipitation titration. Instrumental analysis methods include: 1. Spectral analysis: UV, AA, ICP, fluorescence. . . 2. Chromatographic analysis: gas phase, liquid phase. . . 3. Electrochemical analysis: potentiometry, coulometry, polarography. . . Add 4. Thermal analysis methods: thermogravimetry, differential thermal analysis
