In recent years, due to the strong promotion of the solar photovoltaic cell industry, China's polycrystalline silicon industry has developed rapidly. Dozens of companies have been built, with a production capacity of over 100000 tons/year. The current mainstream production process in the polycrystalline silicon industry is the improved Siemens method, which produces a large amount of low boiling point, highly corrosive, and easily polluting tetrachloride. Therefore, the scientific and efficient utilization of silicon tetrachloride has become an urgent problem to be solved in the polycrystalline silicon industry. One of the ways to achieve effective conversion of silicon tetrachloride is to produce silicon dioxide using silicon tetrachloride. Silica, abbreviated as white carbon black, is non-toxic and odorless. It is an excellent reinforcement filling material and can be widely used in fields such as chemical engineering, materials, medicine, electronic communication, etc. Due to its unique surface structure and appearance, silica with special morphology and hydrophobic modification has continuously gained new applications in drug controlled release, catalyst carriers, polymer miscible filling, sensors, separation engineering, and other fields.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a DC-550 packed column to determine the content of silicon tetrachloride, a byproduct of the polycrystalline silicon industry, and quantifies it using the area normalization method.
