haohan含氢硅油中含氢量的测定5A分子筛不锈钢填充柱6FT*1/8

本文件规定了采用顶空气相色谱法测定含氢硅油中含氢量（Si-H 中 H 的质量分数）的方法。 本文件适用于高含氢硅油、低含氢硅油、端含氢硅油中含氢量的检测。

硅氢键（Si-H）遇氢氧化钾水溶液会产生氢气，氢气的产生量与Si-H中H的含量成正比，化学反应 原理如下。将样品置于密封的顶空瓶中，加入过量的氢氧化钾水溶液，反应生成氢气，通过顶空气相色 谱联用仪，检测出氢气的含量，从而计算出含氢量。

This document specifies the method for determining the hydrogen content (mass fraction of H in Si-H) in hydrogen containing silicone oil using headspace gas chromatography. This document is applicable for the detection of hydrogen content in high hydrogen silicone oil, low hydrogen silicone oil, and end hydrogen silicone oil.
Silicon hydrogen bonding (Si-H) produces hydrogen gas when it encounters potassium hydroxide aqueous solution, and the amount of hydrogen gas produced is proportional to the content of H in Si-H. The chemical reaction principle is as follows. Place the sample in a sealed headspace bottle, add an excess of potassium hydroxide aqueous solution, and generate hydrogen gas through reaction. Use a headspace gas chromatograph to detect the hydrogen content and calculate the hydrogen content.
