热解吸色谱方法现在已成为一种测定固体物质比表面积、比孔体积和孔径分布率的有效方法。在学习我国工作者研制成的ST-03比表面孔分布测定仪的基础上,我们组装了一台热解吸色谱装置。近一年来作了大量的试样的测定,表明本装置使用效果良好。在此装置中用了几个六通阀和几个四通阀组成的多阀系统,代替了单一的六通阀,这样可以连续测定几个试样,提高了测试工作的效率。
Thermal desorption chromatography has now become an effective method for determining the specific surface area, specific pore volume and pore size distribution of solid materials. On the basis of studying the ST-03 surface distribution analyzer developed by our country workers, we assembled a thermal desorption chromatography device. Nearly a year to make a large number of samples measured, indicating that the device with good results. In this device, it uses several multi-valve systems consisting of six-way valves and several four-way valves instead of a single six-way valve so that several test samples can be continuously measured to improve the efficiency of the test work.
