直接法測(cè)定非甲烷總烴 詳細(xì)信息：

名稱：填充柱
固定相：專用
型號(hào)：HH-NMHC
應(yīng)用：直接法測(cè)定非甲烷總烴

鑒于大氣中非甲烷總烴類的有機(jī)物的種種危害，對(duì)污染源、交通要道、工業(yè)園以及 廠界等敏感區(qū)域進(jìn)行非甲烷總烴的實(shí)時(shí)監(jiān)控和管制非常有必要。國(guó)外從上世紀(jì)就開始監(jiān)測(cè) 空氣中的非甲烷總烴的含量，先后發(fā)展了冷凝-重量法、燃燒法、紅外分光法等，但這些技 術(shù)均有其使用限制，操作復(fù)雜等缺點(diǎn)，終未獲得廣泛應(yīng)用。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司，采用直接法測(cè)定非甲烷總烴，無需測(cè)定總烴及甲烷，再通過差量法得出非甲烷總烴的含量，更加準(zhǔn)確，效率高。

Direct method for determination of total non-methane hydrocarbons
Direct method for determination of total non-methane hydrocarbons Details:

Name: Packed column
Stationary phase: dedicated
Model: HH-NMHC
Application: Direct determination of non-methane total hydrocarbons

In view of the various hazards of non-methane total hydrocarbons in the atmosphere, it is very necessary to monitor and control non-methane total hydrocarbons in sensitive areas such as pollution sources, traffic arteries, industrial parks, and factory boundaries. Foreign countries have been monitoring the content of non-methane total hydrocarbons in the air since the last century, and have successively developed condensation-gravity method, combustion method, infrared spectroscopy, etc., but these technologies have their shortcomings such as limited use and complicated operation, and they have not been obtained in the end. widely used.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a direct method to determine total non-methane hydrocarbons, without the need to determine total hydrocarbons and methane, and then obtains the content of non-methane total hydrocarbons through a differential method, which is more accurate and efficient.

Haohan Chromatography provides a complete analysis program
