测空气和废气中甲醇时气相色谱法的改进 详细信息：

空气和废气监测分析方法第五章中甲醇的气相色谱分析方法，应该解决采样时间长（2h）回收效率低和色谱分高存在在拖尾大水峰三个方面的问题。
浩瀚色谱（山东）应用技术开发有限公司通过实验，使用5%Carbowax 20M Carbopack B填充柱、FID检测器等直接进1ml气体样品。方法低检测浓度可达为0．08mg／m3，完全可以替代用水溶液吸收甲醇的色谱分析方法，使用该柱不论是进行水样品的分析还是气体样品的分析，甲醇和乙醇分离效果好，而且不会产生拖尾大水峰。新的色谱分析方法，采样省时间，样品代表性好，分析速度快，分析结果、精密、准确。

Improvement of Gas Chromatography in Measuring Methanol in Air and Waste Gas
Improvement of gas chromatography when measuring methanol in air and exhaust gas. Details:

The gas chromatography analysis method of methanol in Chapter 5 of Air and Waste Gas Monitoring and Analysis Methods should solve the three problems of long sampling time (2h), low recovery efficiency and high chromatographic separation, which are caused by tailing large water peaks.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. passed the experiment and used 5% Carbowax 20M Carbopack B packed column and FID detector to directly enter 1ml gas sample. The minimum detection concentration of the method can reach 0.08mg/m3, which can completely replace the chromatographic analysis method of absorbing methanol with aqueous solution. Whether it is used for the analysis of water samples or gas samples, the separation effect of methanol and ethanol is good, and it is not Large tailing peaks will be produced. The new chromatographic analysis method saves time in sampling, has good sample representativeness, fast analysis speed, and reliable, precise and accurate analysis results.
