毛细管气相色谱法对氢化松节油中主要成分的分析

Analysis of the major components in hydrogenated turpentine by capillary gas chromatography

采用毛细管气相色谱法测定氢化松节油的成分,色谱条件是:氢火焰检测器;BP×5(30mm×0.32mm×0.25μm)柱;柱温75～150℃.测得主要成分为顺式蒎烷、反式蒎烷、α蒎烯、β蒎烯等.分别采用面积归一法和内标法对各组分的含量进行分析,两种定量法的分析结果相近,主要成分蒎烷的顺反比误差小于3%,因此在工业上采用面积归一法就能达到精度要求.

A capillary GC method for the determination of major components in hydrogenated turpentine was described.The conditions for determination were:FID detector,BP×5 capillary column 30m×0.32 mm×0.25 μm film,column temperature 75～150 ℃.The major components are cis pinane,trans pinane,β pinene and α pinene etc.The content of every component was determined by “area percent”method and “internal standard”method,but the rates between cis pinane and trans pinane gotten by the two methods were very close.So in industry,we can use“area percent”method.
