More Information
Summary:The present invention relates to a method for quantitatively analyzing hydrogen gas generated by decomposition of Si-OH (silanol) in porous silica which is a support of a metallocene catalyst. In theanalysis, a content of hydrogen present in trace amounts in silica can be measured by using an inert gas fusion-infrared absorption (IGFIA) method under specific pressure and temperature conditions. 本发明涉及一种氢气的定量分析方法，所述氢气是由作为茂金属催化剂的载体的多孔二氧化硅中Si-OH(硅烷醇)分解而产生的。所述分析通过在特定的压力和温度条件下使用惰性气体熔融-红外吸收(IGFIA)方法可以测量二氧化硅中痕量存在的氢的含量。
