Is there any direction in analytical chemistry that does not require synthesis?

The research of analytical chemistry is mainly to create new analytical methods. Of course, according to the current domestic level, it is difficult to create a new set of analytical methods, such as the fluorescence microscope that won the Nobel Prize last year. Therefore, the research of analytical chemistry still focuses on innovative methods and analyzes some concrete things. I have not been exposed to other nano-analysis, only to environmental and biochemical analysis. Environment, there are many analysis methods. Pretreatment after sampling, supercritical fluid extraction, solid phase extraction, chromatography (GC, HPLC), mass spectrometry and tandem mass spectrometry are many. Include electrochemical analysis. . The residue and complex components were separated and analyzed. Although I do pollution control and prefer materialization, I still can't do without analysis. Biochemical contact, mainly protein omics and metabonomics mass spectrometry analysis. Well, what can I say? You need a level of biological knowledge. For example, protein analysis, extraction is the basic biological means, followed by gel electrophoresis separation, and finally mass spectrometry. But it is still possible.

In fact, there are many methods to analyze, especially for girls, which are unlikely to be non-toxic and harmless, but the toxicity is basically very low. And a wide range of employment. It's just hard to achieve anything. Just like when you enter an enterprise to do analysis, the money is still held by people who do synthetic research and development, and the analysis is basically someone else's. Universities or research institutes can do it, and analysis can do a lot, but compared with materials, it is naturally not as organic as it is. Girls are ok. The employment aspect of the analysis. . . A chemical company needs to do analysis. Including the Food and Drug Administration, all need entry-exit quarantine. The job is relatively stable, and the promotion space depends on the individual. Analytical Chemistry Personally, I think biochemistry and environmental direction are good choices. Nanoprobes are all better.
