HPLC Analysis of Xylitol, Sorbitol and Sucrose on Amaze HD Mixed-Mode Column
Application description

Sugars are polar non-ionic compounds. They are usually analyzed on HILIC columns. We have developed a new column and method for analysis of mono, di- and other saccharides by HPLC. Sugars are retained by a pure HILIC mechanism. The polarity of the stationary phase can be changed based on the pH of the mobile phase and buffer concentrations. The presence of salt is desired to increase the retention time of sugars. In general, monosaccharides will retain less tan di and trisaccharides. The Amaze HD column is compatible with 100% ACN and with 100% water, and can be used either in isocratic or wide gradient modes. This method is robust, reproducible, and allows the analyzation of all polar sugars and other polar compounds on one column.

HPLC Analysis of Sugar Alcohols and Sugars on Amaze HD Mixed-Mode Column
Application description

Sugar alcohols and sugars are carbohydrates which are used in food and can be found in fruits, vegetables and other naturally occurring products. Simple sugars include monosaccharides like glucose, fructose and galactose. Sugar alcohols are derived from sugars and are occurring naturally, or synthesized by hydrogenation of sugars. Both sugars and sugar alcohols are polar with no chromophores. The most common approach for the analysis of sugars and sugar alcohols is HILIC chromatography. These hydrophilic compounds are retained by a polar mechanism on a polar stationary phase like Amaze HD. This column has a very polar group on the surface of silica gel which allows the use of less ACN for the retention of sugars and sugar alcohols. This method and the column can be used for the analysis of sugars and sugar alcohols in fruits, veggies, juices and other beverages. The Amaze HD is compatible with 100% ACN and 100% water. ELSD, CAD, RI or MS are required to retain and monitor sugars.
