&Nbsp&Nbsp&Nbsp; How to simply determine whether a component is organic or inorganic? If the chemical substance is not a polymer or a high molecular weight chemical substance, usually small molecule organic matter should dissolve at 300 ° C. EDX energy depth analysis spectrometer can be used to measure the element content; 2. Take a look under the ultraviolet lamp, if the color can be displayed, it is organic matter, and conversely, it is inorganic matter. Then perform liquid-liquid extraction. Extraction can extract organic components from water, resulting in the vast majority of organic components. Then, the organic phase was further analyzed by GC-MS, and the inorganic elements were further analyzed by ICP-MS. Firstly, judging from the appearance, look at the color, whether there is odor, sediment, whether it is flammable, whether it is corrosive (to metals and glass), and whether it is easily volatile On the other hand, distillation, condensation, and boiling are used to collect non condensing gases for GC-MS, the condensed solution for LC-MS, the remaining crystals for XRD, and the crystals for ICP-MS after acid dissolution; In the end, whether it's organic or inorganic matter, conduct in-depth analysis and comparison (do not use up all the samples during each experiment, try to distill in an oxygen free environment, and provide clues if the color changes after heating and cooling). Let's assume this is an aqueous solution, colorless, tasteless, and not particularly viscous. Does not react with glass containers. You can't have soapy water like foam if you shake the bottle violently. The simplest physical examination can identify a lot of information before starting chemical analysis. Every step of chemical analysis is a waste of money and time, so it is also necessary to prioritize fast and inexpensive methods. More importantly, it is important to minimize the consumption of the test solution as it is a relatively limited resource. So non-destructive testing should be given priority
