气相色谱和快速检测仪测定聚氨酯硬泡中残留的CFC-11和HCFC-141b发泡剂

Determination of Retained CFC-11 and HCFC-141b Blowing Agents in Rigid Polyurethane Foam by Fast Detector and Gas Chromatography

分别采用快速检测仪和气相色谱仪对同一块泡沫中的发泡剂进行检测。快速检测仪因其体积小、质量轻并能快速检出发泡剂的种类，应用于现场监测；气相色谱仪对现场检测样品中的发泡剂进行定量，应用于实验室。结果表明：快速检测仪先用于现场监测，实验室气相色谱仪对有疑问的现场检测样品进行定量，两者结合使用能很好完成市场监督抽查的任务。

Fast detector and gas chromatography were applied to detect the blowing agents in the same foam. Fast detector was used for field monitoring with a small volume, light weight and quick species identification of blo- wing agents. GC was used for determination of blowing agents content in field sample. The results showed that it could finish the market supervision inspection by firstly using fast detector to do field monitoring, then using GC for determination of blowing agent content in suspected samples.
