摘　　要：本文实验选择天然气中微量重烃富集与色谱分析最佳条件。该方法灵敏度高，检测范围大，从ＰＰｂ级到高含量均可一次性分析，富集线性及重复性好从Ｃ＿５─Ｃ＿（１２）可定出１６２个轻烃组分名称，可为油气勘探及有机地化研究提供更多更新的指标。This experinient studies the concentration of micro heavy hydrocarbons in nat-ural gas and the optimum condition of chroniatogrophical analysis. This method featureshigh sensitivity.wide detecting range which enables an analysis amount from ppb to highcontent,good concentration linearity and repeatablility which is capable of discrim in ating162 light hydrocarbon coniponents in C_5─C_(12);and thus providing more new indexes for hy-drocarbon exploration and organic geochemical research.
