| 英文摘要 | an on-line sample introduction technique in capillary gas chromatograph (cgc) for the analysis of high-pressure gas-liquid mixtures has been designed and evaluated. a sample loop of 0.05 mul and a washing solvent loop of 0.5 mul are mounted on a 10-port switching valve, which serves as the injection valve. a capillary resistor was connected to the vent of sample loop in order to maintain the pressure of the sample. both the sample and the washing solvent are transferred into the split-injection port through a narrow bore fused silica capillary inserted into the injection liner through a septum. the volume of the liner is used both as the pressure-release damper and evaporation chamber of the sample. on-line analysis of both reactants and resultants in ethylene olimer reaction mixture at 5 mpa was carried out, which demonstrated the applicability of the technique.
