【摘要】總烴、甲烷和非甲烷總烴分析儀是用于檢測揮發(fā)性有機(jī)污染物的儀器。本文通過高精度動態(tài)配氣裝置獲得甲烷標(biāo)準(zhǔn)氣體,對總烴、甲烷和非甲烷總烴分析儀進(jìn)行測量,并對該分析儀示值誤差測量結(jié)果的不確定度進(jìn)行評定。

【關(guān)鍵詞】總烴、甲烷和非甲烷總烴分析儀;高精度;動態(tài)配氣裝置;不確定度

Abstract: Total hydrocarbon,methane,and non methane total hydrocarbon analyzers are instruments used to detect VOCs. In this paper, a high-precision dynamic gas dispensing device is used to obtain methane standard gas, measure total hydrocarbon, methane, and non methane total hydrocarbon analyzers, and evaluate the uncertainty of the measurement results of the analyzer’s indication error.

Key words: total hydrocarbon; methane and non-methane total hydrocarbon analyzers; high-precision; dynamic gas distribution device; uncertainty

揮發(fā)性有機(jī)污染物(VOCs)一直是我國密切關(guān)注的污染物質(zhì),危害極大,不僅會經(jīng)呼吸影響人體健康,還會通過化學(xué)反應(yīng)影響氣候變化,同時(shí)也是導(dǎo)致光化學(xué)煙霧的因素之一。(剩余1351字)
