摘要:
A method for quantitative analysis of hydrogen gas generated due to the decomposition of Si—OH (silanol) in porous silica, which is a support of a metallocene catalyst is provided. The analysis enables the measurement of the content of hydrogen present in trace amounts in silica by employing an inert gas fusion-infrared absorption (IGFIA) method under specific pressure and temperature conditions.
