Composition analysis: it refers to the technical method of conducting qualitative and quantitative analysis of each component of products or samples by analyzing the components of products or samples through the microscopic spectrogram and laser femtosecond detection of molecular structure. Composition analysis technology is mainly used for the unknown, unknown components were analyzed, such as by composition analysis technology can quickly determine what is target of various components in the samples, the samples to help you to quantitative analysis, qualitative identification, polymer materials such as rubber, raw materials, additives, specific composition and content, foreign bodies, etc.
