名称：填充柱
固定相：专用
规格：3m*3mm，3m*1/8,  3m*4mm
型号：HH-Carbon dioxide-III
应用：食品级二氧化碳中甲醇，氯乙烯，乙醛，环氧乙烷和苯分离专用柱
符合：
1.GB 10621-2006 食品添加剂 液体二氧化碳
2.GB 1886.228-2016 食品安全国家标准 食品添加剂 二氧化碳

依据GB1886.228-2016的国标要求，做食品级二氧化碳杂质分析时，需要对甲醇，乙醛，环氧乙烷，氯乙烯及苯5种物质进行定量分析，然而国标中推荐的色谱柱要不就是乙醛和环氧乙烷合峰(国标中推荐的色谱柱GDX-104)，要不就是氯乙烯和乙醛合峰(国标中推荐的色谱柱硅藻土+10％聚乙二醇)，从而不能很好的对每一个组分进行单一的定性定量分析，因此对以上5种组分的准确定性定量分析一直是色谱分析中的一个难题。

浩瀚色谱（山东）应用技术开发有限公司,善于攻克分析中的疑难问题，依托强大的科研所，研发出新型色谱柱HH-Carbon dioxide-III，一次进样可以对甲醇，乙醛，环氧乙烷，氯乙烯及苯5个组分进行很好的分离和分析，分析时间短，柱效高，峰型对称，达到了准确定性定量分析的良好效果。

此柱为浩瀚色谱，的产品。

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.
