haohan甲烷柱分析环境空气 甲烷、总烃和非甲烷总烃GDX-104

NMHC (non methane total hydrocarbon, Acronym NMHC) is the presence of all hydrocarbons except methane in the ambient air outside the general. Atmospheric NMHC exceeds a certain concentration, in addition to direct harmful to human health, but under certain conditions by the sunlight can produce photochemical smog, environmental and human harm.
When using gas chromatography air NMHC deduction required oxygen interference will produce a positive peak, measured using the packed column filled with methane GDX-104 of the carrier body can be well separated peak oxygen, and can maintain a good stability, in order to obtain the oxygen concentration may also be involved in the calculation of total non-methane hydrocarbons.
Tengzhou City Technology Co., Ltd. Xiangying analysis developed GDX-104 stainless steel column packed with success measured ambient air methane hydrocarbons and total non-methane hydrocarbons, satisfactory results are welcome

 
            非甲烷总烃（non methane total hydrocarbon，缩写NMHC）是存在于环境空气中除甲烷之外的所有碳氢化合物的总称。大气中的非甲烷总烃超过一定浓度，除直接对人体健康有害外，在一定条件下经日光照射还能产生光化学烟雾，对环境和人类造成危害。
        采用气相色谱法检测空气中的非甲烷总烃需扣除会产生正干扰的氧峰，采用填充GDX-104担体的填充柱测甲烷时，可以将氧峰很好的分离出来，且能保持良好的稳定性，以此得出的氧浓度也可参与非甲烷总烃的计算。
