Vertex Column Eurokat Ag                            

Eurokat for food analysis

Eurokat high performance polymer phases were especially developed for the separation of organic acids, carbohydrates, alcohols and even complex mixtures of these compounds.

Eurokat columns require no organic solvents and thus are environmentally friendly.

Eurokat application areas

Four different ionic species are available. Eurokat H is especially designed for the analysis of organic acids and even complex mixtures of acids, sugars and alcohols as well as sugar alcohols. Eurokat Ca and Eurokat Pb are the phases of choice for analysis of smaller carbohydrates (DP < 4), Eurokat Ag is applicable for the separation of sugar oligomers. Eurokat can also be used for the determination of biochemically important molecules such as sugars, artificial sweeteners or acidic metabolic and degradation products. Other application areas include analysis of:

•  carbohydrates and acids in fruit beverages and soft drinks
• sugar substitutes
• food preservatives
• dairy products
• intermediate acids of the Krebs cycle
• urine (uric acid, hippuric acid)
• monitoring of fermentation processes

Stability

Eurokat polymer columns are extremely stable over the whole pH range. This is one striking advantage compared with silica-based phases which have a limited lifetime at pH extremes, especially in the higher pH range. Most importantly, Eurokat phases show extraordinary column lifetime stability and are not affected by aqueous solvents.
