HJ 919-2017 in English

本标准规定了测定环境空气中挥发性有机物的便携式傅里叶红外仪法。
本标准为定性半定量方法，适用于环境空气中丙烷、乙烯、丙烯、乙炔、苯、甲苯、乙苯、苯乙烯等8种挥发性有机物在互不干扰情况下的突发环境事件应急监测。其他挥发性有机物若通过验证也可用本方法测定。
本方法检出限和测定下限见附录A。

Scope

This standard specifies a portable Fourier transform infrared instrument method for the determination of volatile organic compounds in ambient air. This standard is a qualitative and semi-quantitative method, suitable for emergency monitoring of environmental emergencies without interfering with each other, including propane, ethylene, propylene, acetylene, benzene, toluene, ethylbenzene, and styrene. Other volatile organic compounds can also be measured by this method if they pass verification. The detection limit and lower determination limit of this method are shown in Appendix A.
