摘要
利用Restek的Stabilwax型石英毛细管柱,以正戊醇为内标物,通过二次程序升温和氢火焰电离,精确检测高纯度碳酸二甲酯(DMC)样品中各组分的准确浓度。通过实验证明,本文建立的分析体系可以很好地完成样品各组分的高效、准确检测,为高纯度碳酸二甲酯的测定提供了一种新的思路。
The Restek Stabilwax quartz capillary column was used to accurately detect the accurate concentration of each component in high purity dimethyl carbonate(DMC)samples by secondary temperature programmed and hydrogen flame ionization with n-pentanol as internal standard.Through experiments,it is proved that the analysis system established in this paper can well complete the efficient and accurate detection of each component of the sample,which provides a new idea for the determination of high purity dimethyl carbonate.
