设计了一台用来测定有机化合物的气相色谱与红外光谱联用系统。IR吸收池是自制的气体流通池,只用一个四通阀即可将待测组份截留在吸收池中。气相色谱仪(自制)的热导检测器主要用来指示色谱组分的流出时间及数目,IR光谱扫描作结构定性分析。用本系统分析了彩色印刷用的上光纸胶。
A system for the simultaneous determination of organic compounds by gas chromatography and infrared spectroscopy was designed. The IR absorber is a self-made gas flow cell that allows the test component to be trapped in the cell using only one four-way valve. Gas Chromatograph (self-made) thermal conductivity detector is mainly used to indicate the outflow time and number of chromatographic components, IR spectral scanning for structural qualitative analysis. With this system analysis of the color printing paper coated glazing.
