近年来,随着太阳能的不断发展,生产太阳能电池的原材料—多晶硅,也随之得到迅速发展。多晶硅的生产方法主要有改良西门子法、硅烷法、冶金法等。我国主要采用改良西门子法生产多晶硅,该方法生产工艺相对成熟。但核心技术仍掌握在国外发达手中,尤其是尾气干法回收工艺,能耗高,设备维护费用高。因此,降低多晶硅生产过程尾气干法回收装置的能量消耗,具有重大的意义。

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hua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hua氢进行测定。目前测定氯hua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hua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。

滕州市浩瀚色谱仪器技术服务有限公司，研发出《HH-1毛细管柱测定氢气中的氯hua氢/HCL》，峰形对称，结果满意。

In recent years, with the continuous development of solar energy, the production of polysilicon, a raw material for solar cells, has also developed rapidly. The production methods of polycrystalline silicon mainly include improved Siemens method, silane method, metallurgy method and the like. China mainly uses the modified Siemens method to produce polycrystalline silicon. The production process of this method is relatively mature. However, the core technology is still in the hands of foreign developed countries, especially the dry gas recovery process, high energy consumption and high equipment maintenance costs. Therefore, it is of great significance to reduce the energy consumption of the exhaust gas dry recovery device in the polysilicon production process.
In the production of polysilicon, the dry process recovers hydrogen as the raw material reducing agent and carrier gas. If the chlorine and hydrogen content is high, the furnace may appear in the early stage of the polysilicon production process. Phosphorus exceeding the standard may occur in the later stage, which seriously affects the quality of polysilicon. . Therefore, it is necessary to measure the chlorine hydrogen in the recovered hydrogen. At present, the methods for determining chlorohua hydrogen include ion chromatography, spectrophotometry, infrared spectroscopy and packed column gas chromatography. When ion chromatography is used, chlorohua hydrogen is converted to Cl- for detection, and the operation is cumbersome and gas-consuming. Big, long time and other shortcomings.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. developed the "HH-1 capillary column for the determination of chlorohua hydrogen/HCL in hydrogen". The peak shape is symmetrical and the results are satisfactory.
