摘要

本方法主要根据Kolb提出的固体中挥发组份相平衡及不连续气体抽提理论,参照Schaefer等人的氢抽提方法,改进收集系统和毛细柱系统而建立。可测定泥岩、灰岩等沉积岩中C2-C9烃类,最低检测量对丙烷为lPPb,C2-C9总烃测定误差小于20%。

Abstract

This method is a Modification of the hydrogen extraction method of Schaefer et al.and referring to the theory of the phase balance of volatile component in solids and the discrete gas extraction suggested by Kolb. This method can be used to determine C2-C9 hydrocarbons in the sedimentary rocks, limestone etc. The limit of detection is I ppb. The error in determination of the total amount (C2-C9) is 20%.
