GB/T 9009-2011 Determination of methanol in industrial formaldehyde solution
GB/T 9009-2011 Determination of methanol in industrial formaldehyde solution Details:

Name: Packed Column
Stationary Phase: Polymer Microspheres
Granularity: 60-80 mesh
Material: Stainless steel
Specifications: 2m* (Φ3mm-- Φ4mm)
Model: GDX-403
Application: GB/T 9009-2011 Packed column for the determination of methanol in industrial formaldehyde solution

GB/T 9009-2011 Formaldehyde solution for industrial use
This standard replaces GB/T 9009-1998 Industrial formaldehyde solution
This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, safety, etc. of industrial formaldehyde solution.
This standard applies to industrial formaldehyde solution obtained by methanol oxidation.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatographic analysis method for the determination of formaldehyde and methanol content in industrial formaldehyde, and obtained stable industrial formaldehyde chromatographic analysis conditions through experimental optimization. The system error between national standard titration analysis, the improved chromatographic analysis method significantly shortens the analysis time, and improves the accuracy and precision of the analysis.
