What are the similarities and differences between chemical analysis and instrumental analysis?
Now the trend of analytical chemistry is instrumental analysis, and chemical analysis is more applied in teaching. At the same time, chemical analysis is slowly developing toward instrument automation, such as automatic titration now.
Different:Chemical analysis is a quantitative or qualitative branch of analytical chemistry based on four conventional titrations, namely, redox titration, complexometric titration, acid-base titration, and precipitation titrations.Instrumental analysis is a method of analysis based on the physical and physico-chemical properties of matter. Qualitative analysis, quantitative analysis and morphological analysis of substances were carried out by using special instruments. Instrumental analysis methods include many analytical methods, and there are currently ten kinds. Each method of analysis is based on different principles, the measured physical quantity is different, the operation process and application are also different. Common analytical instruments are spectrum instruments (AAS, ICP, etc.), chromatography instruments (GC, LC, etc.), nuclear magnetic resonance spectroscopy, coulometric analysis, polarography, and so on.
The same: they are the branches of Analytical Chemistry
