& Rubber component analysis requires the most advanced analytical instruments to ensure objective accuracy, and the most authoritative and comprehensive atlas database to provide analysis cases. It also requires engineers with many years of development experience to analyze and calculate based on the objective data of the first two before final analysis. Determine the specific composition of the sample. A component analysis method that qualitatively and quantitatively identifies the components contained in the product through microscopic spectra (gas chromatography, liquid chromatography, thermal spectrum, energy spectrum, nuclear magnetic resonance spectrum, etc.)
