Separation of diastereoisomers of acyclic isoprenoid alkanes by GC-MS and optimization of operation conditions
摘要
Abstract
The separation of diastereoisomers of acyclic isoprenoid alkanes on HP-5 columns was firstly reported by gas ehromatography and mass speetrometry (GC-MS). The biomarkers of saturated hydrocarbons from coal samples of the Junggar Basin and crude oils of Gudao area were determined, and iC18(2,6,10-trimethyl penta-decane) , Pr (2,6,10,14-tetramethyl pentadecane) , Ph (2,6,10,14-tetramethyl hexadecane) and their diastereoisomers were identified from coal samples and crude oils. The effects of type and length of chromato-graphic column and temperature programming on the separation of diastereoisomers of acyclic isoprenoid alkanes were investigated. The most favorable separation conditions were concluded. The diastereoisomers were separated from nor-pristane, Pr and Ph, and the maximal resolution factors of Pr and Ph are 0.7, 0.9, respectively.关键词
