| 中文摘要: |
| 气相色谱法测定废气中非甲烷总烃，国内外相关标准选用的标准气体各不相同，通过试验考察各标准气体对测定的影响，并比对相关文献信息。结果表明：甲烷和丙烷（浓度以碳计）在填充柱气相色谱仪和毛细管柱气相色谱仪FID检测器上的响应无明显差异，而采用甲烷作为标准气体，分析时间短，工作效率高。 |
| 英文摘要: |
| In the national and abroad standard methods of detecting non methane hydrocarbons in waste gas by gas chromatography, different standard reference gases were selected. Experimental data and standards comparison results showed that: CH4 and C3H8 had the same response values as carbon on the FID detector. Using methane as the standard gas, the analysis time was short, and the work efficiency was much high. |
