haohan环境空气非甲烷总烃连续自动监测HH-NMHC-1甲烷复合柱1m*1/8

非甲烷总烃(NMHC)作为挥发性有机物总量判断的重要指标,其结果测定的准确性至关重要。传统的气相色谱法为2根色谱柱，分别测定总烃和甲烷的含量，然后差减法计算非甲烷总烃的含量，操作复杂，费时费力，效率低下，无法满足大规模生产检测的需要。

浩瀚色谱（山东）应用技术开发有限公司，与时俱进，研发独树一帜的十通阀反吹气相色谱法单柱直接气相色谱法测定环境空气中非甲烷总烃，柱效高，分离好，效率高，结果满意。

As an important indicator to judge the total amount of volatile organic compounds, non-methane total hydrocarbons (NMHC), the accuracy of the results is very important. The traditional gas chromatography method uses two chromatographic columns to measure the content of total hydrocarbons and methane respectively, and then calculate the content of non-methane total hydrocarbons by subtraction. The operation is complicated, time-consuming and labor-intensive, and the efficiency is low, which cannot meet the needs of large-scale production testing.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a unique ten-port valve backflushing gas chromatography single-column direct gas chromatography method for the determination of non-methane total hydrocarbons in ambient air, with high column efficiency, good separation and high efficiency high, the results are satisfactory.
