丙烯中二氧化碳含量分析方法改进

The Propylene Carbon Dioxide Content Analysis Methods to Improve

目前,丙烯产品来源广泛,各生产厂家的丙烯质量参差不齐,尤其是其中二氧化碳的含量差别巨大。我们根据现有条件,采用TCD和FID相结合的气相色谱法对丙烯中的二氧化碳进行分析,通过严控二氧化碳含量,现在原料丙烯中的二氧化碳含量已经严格控制在指标范围之内。

At present, the propylene extensive sources, propylene quality manufacturers uneven, especially carbon dioxide in a huge difference. We according to existing conditions, using TCD and FID combination of gas chromatography analysis of propylene in carbon dioxide, the carbon dioxide content through strict control, now the carbon dioxide content in raw material has been strictly controlled in the target range.
