中文名称：天然气分析 生物甲烷 用微气相色谱法测定萜烯含量

英文名称：Analysis of natural gas — Biomethane — Determination of terpenes' content by micro gas chromatography

发布日期：2023-08

标准范围

本文件规定了在线或离线测定生物甲烷中五种萜烯含量的微量气相色谱法，即:—？α-蒎烯、—？β-松脂，—？副甲苯，—？柠檬烯、—？3-卡琳。该方法是专门针对这五种化合物开发的。有关化合物的信息见附件？A.该方法适用于5种萜烯的单个量分数的测定？μ mol/mol不超过10？微摩尔/摩尔。稍加修改，它也可用于萜烯含量高于10？微摩尔/摩尔。

This document specifies a micro gas chromatography method for the on-line or offline determination of the content of five terpenes in biomethane, namely:

—     alpha-pinene,

—     beta-pinene,

—     para-cymene,

—     limonene,

—     3-carene.

The method is specifically developed for these five compounds. Information about the compounds is given in Annex A.

The method is applicable to the determination of individual amount fractions of the five terpenes from 1 μmol/mol up to and including 10 μmol/mol. With minor modifications it can also be used for terpene amount fractions above 10 μmol/mol.
