【摘要】 选用正十二烷为内标物,采用内标法对α-蒎烯、β-蒎烯、对伞花烃和长叶烯进行了定量分析。确定了最优的气相色谱分析条件,分别测定了α-蒎烯、β-蒎烯、对伞花烃和长叶烯的相对质量校正因子和线性回归相关系数。用内标法和面积归一法分别对试样进行了定量分析,结果表明两者误差小于2.33%。更多还原

【Abstract】 A method was introduced for quantitative analysis of α-pinene,β-pinene,p-cymene and longifolene by 1102-Gas Chromatograph with the n-dodecane as internal standard.The optimal conditions for GC analysis were confirmed and the relative mass correction factors and the linear correlation coefficients of α-pinene,β-pinene,pcymene and longifolene were determined.Internal standard method and area nomalization method were used to determine the sample,respectively and the result showed that the relative error was less than 2.33 %.更多还原
