Based on the principle of phase equilibrium, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established an analytical method for the content of residual trimethylamine in phenolic polymer composites. The testing process includes pretreatment, extraction and gas chromatography analysis. After a certain pretreatment, the composite material was kept at a constant temperature for 16 h, and the trimethylamine adsorbed in it was fully transferred to the liquid phase. Finally, the concentration of trimethylamine in the liquid phase was tested by gas chromatography. The method is accurate and sensitive, and the test results meet the requirements of microanalysis, which can be used for the test of actual samples.
