Our Analysis And Detection Methods

Alfa Chemistry masters a variety of silicone analysis and detection methods. Among them, our typical detection methods are as follows:

Gas chromatography (GC): GC mainly uses the differences in boiling point, polarity and adsorption properties of substances to separate mixtures. In the development process of silicone products, GC is mainly used to analyze small molecular substances, such as silanes, linear or cyclic silicone polymer small molecules with low polymerization degree.

Infrared spectroscopy (IR): IR has the advantages of high resolution and reliability, and is suitable for the analysis and detection of various silicone samples. By detecting the energy absorbed by a sample under different infrared light, the structure and composition of silicone can be determined.

Nuclear magnetic resonance spectroscopy (NMR): NMR is a technique used to analyze the molecular structure and complexity of compounds. This method has the characteristics of high sensitivity and high resolution, and can complete sample analysis in a very short time. Commonly used nuclear magnetic resonance spectra include ¹H-NMR, ¹³C-NMR and ²⁹Si-NMR.

Mass Spectrometry (MS): MS is a technique used to determine molecular weight and structure. By analyzing the relative molecular mass and intensity of ion peaks in silicone samples, the structure and composition of silicone can be determined. For difficult-to-volatile liquid or solid silicone polymers, it is very effective to use MS to obtain information about their composition and structure.

In addition, we also analyze and detect silicone samples through high-performance liquid chromatography (HPLC), ultraviolet-visible spectroscopy (UV-Vis), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electrochemical analysis, fluorescence spectroscopy, etc.
