GB/T 9009-2011 工业用甲醛溶液
本标准代替GB/T 9009-1998 工业甲醛溶液
本标准规定了工业用甲醛溶液的要求、试验方法、检验规则、标志、包装、运输、贮存、安全等。
本标准适用于由甲醇氧化法制得的工业用甲醛溶液。

浩瀚色谱(山东)应用技术开发有限公司建立了工业甲醛中甲醛和甲醇含量测定的气相色谱分析方法,通过实验优化得到稳定的工业甲醛色谱分析条件,实验中对比了工业甲醛色谱分析法改进前后与国标滴定分析之间系统误差,改进后色谱分析法明显缩短了分析时间,提高了分析的准确度和精密度。

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.
