1. Ca column
Calcium columns are the preferred column for general sweetener analysis. It has been optimized for the analysis of monosaccharides and provides separation of disaccharides, trisaccharides and tetrasaccharides. The 300 x 7.8 mm column is primarily used to quantify glucose and fructose in high fructose corn syrup, as well as routine analysis of monosaccharides. The 250 x 4.0 mm column is suitable for sugar alcohol separation.
2. H column
Hydrogen-type columns are used for the analysis of carbohydrates in solutions containing carboxylic acids, volatile fatty acids, short-chain fatty acids, alcohols, ketones, and many neutral metabolic by-products. Most commonly used for organic acid analysis, this column can also be used for fermentation monitoring, biological fluid analysis, and acetyl glucosamine separation.s
3. Pb column
Lead-type columns are specifically designed to separate cellulose-derived monosaccharides. It is used to analyze pentose and hexose in wood products, especially cellobiose, glucose, xylose, galactose, arabinose and mannose. It also provides a good distinction between sucrose, lactose and fructose in dairy products.
4. Na column
Sodium columns have been optimized for sugar analysis in samples containing high concentrations of salts such as beet sugar. It is compatible with the salt, so the sample does not need to be desalted prior to analysis.
5. K column
Potassium columns have been optimized for monosaccharide, disaccharide, and trisaccharide analysis in samples such as corn syrup and brewed wort. It is a good separation of glucose, maltose and maltotriose.
6. Ag column
The silver column provides fast, high resolution oligosaccharide analysis. It separates the oligosaccharide (Dp-11) in approximately 25 minutes.
7. NH column
The amino column is generally used for separating various monosaccharides, and it is not suitable to separate an aldehyde group, a carbonyl compound, a reducing sugar, and can be used for separating non-reducing sugars
