5%Carbowax20M Carbopack B 固定污染源排气中甲醇的测定 气相色谱法的详细资料

固定污染源排气中甲醇的测定 气相色谱法
固定污染源排气中甲醇的测定 气相色谱法 详细信息：

浩瀚色谱（山东）应用技术开发有限公司，对目前甲醇分析方法存在的问题,通过大量研究试验提出了"空气中的甲醇被水吸收后，适用于环境空气与工业污染源排放废气中甲醇的测定,方法的检测限为0.5μg/5ml,以0.5L/min的流量,采集30L空气,最低检出浓度为0.016mg/m3"。该法较现行的测试方法明显地体现出了"速度快、操作简便、灵敏度和准确度高、重现性好、线性范围较宽的测试优势。

This standard is applicable to the determination of trimethylamine in the exhaust gas of odor pollution sources and the ambient air of factories. When the sampling volume is 10L, the minimum detectable concentration of the method is 2.5-3 × 10mg/m3. This standard determines the presence of trimethylamine in a gaseous state. The amine compounds such as ammonia, methylamine, ethylamine, and dimethylamine in the sample do not interfere with the determination of trimethylamine under the chromatographic conditions selected in this method.

Determination of Methanol in Exhaust from Fixed Pollution Sources by Gas Chromatography
Determination of methanol in exhaust gas from fixed pollution sources by gas chromatography. Detailed information:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has proposed through extensive research and experimentation that "methanol in the air, after being absorbed by water, is suitable for the determination of methanol in environmental air and industrial pollution source emissions. The detection limit of the method is 0.5 μ g/5ml, and 30L of air is collected at a flow rate of 0.5L/min, with a minimum detection concentration of 0.016mg/m3. This method clearly demonstrates the advantages of "fast speed, easy operation, high sensitivity and accuracy, good reproducibility, and wide linear range" compared to current testing methods.
