摘要
利用便携式气相色谱技术,建立了固定污染源废气中非甲烷总烃(NMHC)的现场快速测定方法。方法检出限为总烃0.07 mg/m ^3,甲烷0.06 mg/m ^3,NMHC 0.07 mg/m^ 3。该方法操作简单,用时短,检测结果准确可靠,适用于固定污染源NMHC的现场快速测定。
A rapid on-site method for the determination of non-methane total hydrocarbons(NMHC)from stationary source emission was established by using portable gas chromatography.The detection limits were 0.07 mg/m ^3 for total hydrocarbons,0.06 mg/m^ 3 for methane and 0.07 mg/m^ 3 for NMHC.The method is simple,time-consuming,accurate and reliable.It is suitable for rapid determination of NMHC from stationary source emission.
