                    非甲烷總烴(NMHC)作為揮發性有機物總量判斷的重要指標,其結果測定的準確性至關重要。浩瀚色譜(山東)應用技術開發有限公司研究在其他測試條件一致的情況下,使用經惰性化處理的閥和未經惰性化處理的閥分別進樣,對標準樣品、無組織排放監控點空氣樣品和有組織排放廢氣進行測試。結果表明:未經惰性化處理的進樣閥對標氣等單一組分影響較小,對多組分、復雜實際空氣和廢氣樣品結果影響較大;經惰性化處理的進樣閥對標氣和復雜樣品的結果準確性影響較小。因此,在NMHC測定時,建議選擇經惰性化處理的進樣閥、進樣管路和定量環,以減少對NMHC測定的影響。

                    Non methane hydrocarbon (NMHC) is an important indicator for the determination of total volatile organic compounds (VOCs), and the accuracy of its results is crucial. Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. studied that under the same conditions of other tests, the standard samples, the air samples from unorganized emission monitoring points and the exhaust gases from organized emissions were tested by using the valves that have been inerted and the valves that have not been inerted to inject samples respectively. The results show that the sample valve without inerting treatment has little influence on the single component such as standard gas, but has great influence on the results of multi-component, complex real air and waste gas samples; The inert injection valve has little influence on the accuracy of the results of standard gas and complex samples. Therefore, it is recommended to select the inert injection valve, injection pipeline and quantitative ring to reduce the impact on NMHC determination.
