多晶硅生产中,干法回收氢气作为原料还原剂和载流气体,若其中氯化氢含量高,则在多晶硅生产过程的前期可能出现倒炉现象,后期可能出现磷超标现象,严重影响多晶硅的质量。因此需对回收氢气中的氯化氢进行测定。目前测定氯化氢的方法有离子色谱法、分光光度法、红外光谱法和填充柱气相色谱法等,采用离子色谱法时需将氯化氢转化为Cl-进行检测,存在操作繁琐、耗气量大、耗时长等缺点。

In the production of polysilicon, the dry recovery of hydrogen is used as the raw material reducing agent and carrier gas. If the content of hydrogen chloride is high, the furnace may be turned down in the early stage of the polysilicon production process, and the phosphorus excess may occur in the later stage, which will seriously affect the quality of polysilicon. Therefore, it is necessary to measure the hydrogen chloride in the recovered hydrogen. At present, the methods for the determination of hydrogen chloride include ion chromatography, spectrophotometry, infrared spectroscopy and packed column gas chromatography, etc. When using ion chromatography, it is necessary to convert hydrogen chloride into Cl- for detection, which is complicated in operation, large in gas consumption, and time-consuming. and other shortcomings.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a unique special packed column for the determination of hydrogen chloride content in hydrogen, with high column efficiency, good separation, symmetrical peak shape, quantitative external standard method, accurate and reliable results. satisfy.
