The field of identification of unknown objects
Unknown component analysis (also known as "unknown substance analysis") is a qualitative and quantitative analysis of the composition of complex unknown chemicals through comprehensive separation and analysis means, providing scientific basis for scientific research, formulation research, product development, and improvement of production process, and providing strong technical support for the introduction, digestion, absorption and innovation of enterprises. Unknown component analysis refers to the technical method of analyzing unknown components by spectrogram. This technology is similar to the "reverse engineering" in the legal field, through disassembling, testing and reassembling the target product to achieve the purpose of restoration.
