Separate methanol, acetaldehyde, ethylene oxide, vinyl chloride and benzene from CO2
Separation of methanol, acetaldehyde, ethylene oxide, vinyl chloride and benzene from CO2 Details:

Name: Packed column
Stationary phase: dedicated
Specifications: 3m*3mm, 3m*1/8, 3m*4mm
Model: HH-Carbon dioxide-III
Application: Special column for separation of methanol, vinyl chloride, acetaldehyde, ethylene oxide and benzene in food grade carbon dioxide
conform to:
1.GB 10621-2006 food additives liquid carbon dioxide
2.GB 1886.228-2016 National Food Safety Standard Food Additive Carbon Dioxide

According to the GB1886.228-2016 national standard requirements, when doing food-grade carbon dioxide impurity analysis, it is necessary to quantitatively analyze five substances: methanol, acetaldehyde, ethylene oxide, vinyl chloride and benzene. However, the chromatographic column recommended in the national standard is not required. It is the combined peak of acetaldehyde and ethylene oxide (the column GDX-104 recommended in the national standard), or the combined peak of vinyl chloride and acetaldehyde (the column diatomite recommended in the national standard + 10% polyethylene glycol) Therefore, a single qualitative and quantitative analysis of each component cannot be performed well. Therefore, accurate qualitative and quantitative analysis of the above five components has always been a difficult point in chromatographic analysis.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. is good at overcoming difficult problems in analysis. Relying on powerful scientific research institutes, it has developed a new type of chromatographic column HH-Carbon dioxide-III, which can treat methanol, acetaldehyde, and ethylene oxide in one injection. The five components of alkane, vinyl chloride and benzene are well separated and analyzed. The analysis time is short, the column efficiency is high, and the peak shape is symmetrical, which achieves a good effect of accurate qualitative and quantitative analysis.

This column is a unique product of Haohan Chromatography.
