便携式设备在VOCs现场检测中的应用

Application of portable device in VOCs field detection

随着各级环保部门对VOCs的检测管理越来越重视,传统的VOCs监测方法存在耗时长、检测偏差大、瞬时样品无代表性等诸多缺点已无法满足VOCs现场监测快速、准确的需求,使用便携式设备现场监测是目前的最新趋势。本文主要介绍了便携式防爆总烃分析仪及便携式非甲烷总烃析仪的特点及两款设备在VOCs检测现场的应用。便携式设备以其体积小、重量轻的特点,能对VOCs进行现场直接分析测定,完全避免了VOCs检测过程中的样品的保存问题,满足VOCs现场监测快速、准确的需求及环保执法、事故现场调查等现场对监测代表性和时效性的要求,具有广阔的应用前景。

With more and more attention paid by environmental protection departments at all levels to the detection and management of VOCs,the shortcomings of traditional VOCs monitoring methods,such as time-consuming,large deviation,non-representativeness of instantaneous samples and so on,can not meet the rapid and accurate requirements of VOCs on-site monitoring.The use of portable equipment on-site monitoring is the latest trend.This paper mainly introduces the characteristics of portable explosion-proof total hydrocarbon analyzer and portable non-methane total hydrocarbon analyzer and the application of these two equipments in VOCs detection field.Portable equipment with its characteristics of small volume and light weight can be used for on-site direct analysis and determination of VOCs,completely avoiding the preservation of samples in the process of VOCs detection,meeting the requirements of rapid and accurate VOCs onsite monitoring,environmental protection law enforcement,accident on-site investigation and other on-site monitoring representativeness and timeliness.Portable devices have broad application prospects.
