名稱：填充柱
固定相：專用
規(guī)格：3m*3mm，3m*1/8,  3m*4mm
型號：HH-Carbon dioxide-III
應(yīng)用：食品級二氧化碳中甲醇，氯乙烯，乙醛，環(huán)氧乙烷和苯分離專用柱
符合：
1.GB 10621-2006 食品添加劑 液體二氧化碳
2.GB 1886.228-2016 食品安全國家標(biāo)準(zhǔn) 食品添加劑 二氧化碳

依據(jù)GB1886.228-2016的國標(biāo)要求，做食品級二氧化碳雜質(zhì)分析時，需要對甲醇，乙醛，環(huán)氧乙烷，氯乙烯及苯5種物質(zhì)進行定量分析，然而國標(biāo)中推薦的色譜柱要不就是乙醛和環(huán)氧乙烷合峰(國標(biāo)中推薦的色譜柱GDX-104)，要不就是氯乙烯和乙醛合峰(國標(biāo)中推薦的色譜柱硅藻土+10％聚乙二醇)，從而不能很好的對每一個組分進行單一的定性定量分析，因此對以上5種組分的準(zhǔn)確定性定量分析一直是色譜分析中的一個難題。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司,善于攻克分析中的疑難問題，依托強大的科研所，研發(fā)出新型色譜柱HH-Carbon dioxide-III，一次進樣可以對甲醇，乙醛，環(huán)氧乙烷，氯乙烯及苯5個組分進行很好的分離和分析，分析時間短，柱效高，峰型對稱，達到了準(zhǔn)確定性定量分析的良好效果。

此柱為浩瀚色譜，的產(chǎn)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.
