如何保证在线气相色谱仪能够得到准确的分析数据是个十分重要的问题 ,分析仪的温度、载气的流速和纯度、样品的气化程度、标准气体的混合均匀程度以及色谱处理参数等诸多因素都将对此产生影响。结合聚丙烯生产过程中的丙烯中氢气含量在线气相色谱仪 ,对这一问题进行比较全面的讨论。
How to ensure that the on-line gas chromatograph can obtain accurate analytical data is a very important issue. The temperature of the analyzer, the flow rate and purity of the carrier gas, the degree of gasification of the sample, the mixing degree of the standard gas and the parameters of the chromatographic treatment are all factors Will have an impact on this. Combined with the on-line hydrogen gas content of propylene in polypropylene production, a more complete discussion of this issue is given.
