在长波长光通信研究中,光导纤维中含氢氧基量对光的衰耗有极为严重的影响。制作光纤的主要原料(四氯化硅)中含氢及含碳氢化合物是氢氧基形成的重要原因之一,这方面的研究已引起分析工作者的重视。实验方法与结果 1.仪器与试剂: (1)仪器:英国Pye Unicam204系列色谱仪。氢的测定:热导池检测器(室温),1米×3毫米5A分子筛(30—60目)柱,柱温室
In long-wavelength optical communications research, the amount of hydroxyl groups contained in optical fibers has a very serious effect on the attenuation of light. One of the important reasons for the formation of hydrogen and hydrocarbon containing hydrogen in the main raw material for making optical fiber (silicon tetrachloride) has been drawn by analysts. Experimental methods and results 1. Instruments and reagents: (1) Instrument: Britain Pye Unicam204 Series Chromatograph. Hydrogen Determination: Thermal conductivity cell detector (room temperature), 1 x 3 mm 5A molecular sieve (30-60 mesh) column, column greenhouse
