A field of analytical chemistry that focuses on the analysis of organic compounds. There are qualitative analysis, which determines the types of elements and functional groups contained, and quantitative analysis, which determines their composition and content. In addition to chemical methods such as elemental analysis and functional group analysis, which examine the behavior and substances produced when a sample is burned or reacted with various reagents, various physical methods are also used. Representative physical methods include ultraviolet absorption spectroscopy, infrared absorption spectroscopy, Raman spectroscopy, nuclear magnetic resonance absorption spectroscopy, mass spectroscopy, and X-ray analysis.
