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.
