食品添加劑專用填充柱的研制
食品添加劑專用填充柱的研制 詳細信息：

固定相：專用
規格：2m*3mm
型號：HH-SPJ-II
應用：食品添加劑山梨酸/苯甲酸測定

食品添加劑的安全問題已引起人們廣泛地關注。山梨酸、苯甲酸是使用為廣泛的一類食品防腐劑,其檢測方法采用國標GB/T 5009.29-2003中的色譜柱為玻璃填充柱5%DEGS+1%H3PO4,玻璃填充色譜柱有易碎,使用壽命短等缺點。
滕州市浩瀚色譜儀器技術服務有限公司，通過對色譜柱的特殊處理和鈍化脫活,采用混合固定液法,研制了一種的氣相填充色譜柱,經測試表明,該色譜柱性能優異完全滿足國標中對山梨酸、苯甲酸檢測的要求。

Development of a special packed column for food additives
Development of a special packed column for food additives

Stationary phase: dedicated
Specification: 2m*3mm
Model: HH-SPJ-II
Application: Determination of food additive sorbic acid/benzoic acid

The safety of food additives has caused widespread concern. Sorbic acid and benzoic acid are the most widely used food preservatives. The detection method adopts the column of national standard GB/T 5009.29-2003 as glass filled column 5% DEGS+1%H3PO4, and the glass-filled column has brittleness. Shortcomings such as short service life.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., through the special treatment and passivation deactivation of the column, a new type of gas-filled column was developed by using the mixed fixative method. The test showed that the column has excellent performance. Meet the requirements of the national standard for the detection of sorbic acid and benzoic acid.
