室内环境污染物 TVOC 检测条件研究

摘要

This paper describes how to select the best sampling conditions for TVOC from the"sampling flow rate and sampling time", and how to select "the ratio of hydrogen and air flow and makeup flow in gas chromatography"to determine the best instrument sensitivity.%本文主要讲述如何通过＂采样流量及采样时间＂来选择TVOC的最佳采样条件、以及如何选择＂气相色谱仪氢气与空气流量的比例、尾吹流量＂来确定仪器最佳灵敏度。
