生物油主要化学成分的定量分析

Quantitative analysis of main chemical components

利用气相色谱仪分析生物油的主要化学成分,如醋酸、糠醛和羟基丙酮,建立定量分析方法.结果表明:一定的色谱条件和测试的浓度范围,三者的定量标准曲线都呈现良好的线性关系,相关系数大于0.999,相对标准偏差小于3%.该方法快速、准确、重现性好.

A quantitative analysis method of main components of bio-oil was established by using a gas chromatograph.These components included acetic acid,furfural and acetol.The results showed that the quantitative standard curve of these three components had a good linear under a certain chromatography condition and concentration range of samples.The linear correlation coefficient for these three components reached to 0.999,and the relative standard deviations were less than 3%.All these suggested that the analysis method was rapid,accurate and repeatable.
