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.

The present invention relates to a method for quantitatively analyzing Cl, remaining after synthesis, in zinc ferrite synthesized using chloride precursors such as zinc chloride and iron chloride, and provides a method capable of using, in a quantitative analysis method of Cl remaining after synthesis of an inorganic material, AQF-IC, which has been used only in the quantitative analysis of an organic sample since gaseous Cl, discharged after burning zinc ferrite in an automatic quick furnace (AQF) by using an Sn capsule and tungsten oxide (WO3), is analyzed through ion chromatography (IC).
