Preservative Analysis Chromatography Column

[GB 5009.28-2016 National Food Safety Standard Determination of Benzoic Acid, Sorbic Acid, and Sodium Saccharin in Foods]

[GB 5009.121-2016 National Food Safety Standard Determination of Dehydroacetic Acid in Foods]

BST-C18 is a newly developed chromatography column by , specifically designed for the detection of preservatives. It employs a polar small molecule end-capping technique to reduce the bonding density of C18, which enhances the hydrophilicity of the filler material and aims to slow down the rate of contamination in the chromatography column. This design extends the column's service life and improves its durability for preservative detection applications. Even after consecutive injections of over a thousand samples, the column still maintains outstanding peak shape and resolution.

AAA HPLC Column

The Amino Acid Analysis Column is a chromatography column developed by , specifically designed for the detection of amino acids. Its accompanying method package utilizes the pre-column derivation method with phenylisothiocyanate (PITC), offering the following advantages: (1) PITC has good stability, can be stored for half a year at 2-8°C, and avoids the hassle of frequent replacement or preparation due to the expiration of the derivative reagent; (2) the mobile phase pH is 6.5 (±0.05), which is conducive to extending the life of the chromatography column and reducing costs. The AAA Method Package can be widely applied to the detection of amino acids in biological fermentation broth, feed, amino acid injections, food, and beverages.
