名称：毛细管柱
固定相：极性多孔共聚物键合（聚乙烯苯-二乙烯基苯）
规格：25m*0.32妈妈*7um
型号：HH-PLOT U
应用：GB/T 9009-2011 工业用甲醛溶液中甲醇的测定毛细管柱气相色谱法

浩瀚色谱（山东）应用技术开发有限公司以HH-PLOT U为固定相,以N_2为载气,用FID检测器气相色谱法,使甲醛-水-甲醇三组分分离。以色谱柱的分离度作为分离效率的指标,研究柱温及载气流速对分离度的影响,确定的操作条件。在此基础上采用标准曲线法进行了定量。

Determination of methanol content in formaldehyde by gas chromatography
Determination of methanol in formaldehyde by gas chromatography Details:

Name: capillary column
Stationary phase: polar porous copolymer bonded (polyvinylbenzene-divinylbenzene)
Specifications: 25m*0.32mother*7um
Model: HH-PLOT U
Application: GB/T 9009-2011 Determination of methanol in industrial formaldehyde solution by capillary column gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used HH-PLOT U as the stationary phase and N_2 as the carrier gas to separate formaldehyde-water-methanol three components by gas chromatography with FID detector. Taking the separation degree of the chromatographic column as the index of separation efficiency, the effects of column temperature and carrier gas flow rate on the separation degree were studied, and the optimal operating conditions were determined. On this basis, the standard curve method was used for quantification.
