二甲脲的高效液相色谱分析

利用普通的C18柱分析二甲脲，经济实用并且有效。分析的精密度、线性均良好（R=0.99987）。此方法所得分析结果与亚硝酸钠法分析结果保持一致，并可从谱图中直接得到二甲脲等杂质的相对百分含量，有助于生产上的控制。

Determination of Dimethyl Urea by High Performance Liquid Chromatography

The determination of dimethyl urea by general ODS column is economical, applicable and efficient. The precision and the linearity are all good （R=0.99987）,The determination result by this method is in line with that by sodium nitrite titrimetry. And we can get the comparative percentage of impurity such as methyl urea from the chromatoqraphy directly, This will be helpful in controlling the process of production.
