Benson BP-800 Ca, Calcium Form, 300 mm x 7.8mm, 9 µm

The Benson BP-800 Ca HPLC column (300 × 7.8 mm, 9 µm) is based on a more highly cross-linked sulphonated styrene-divinylbenzene matrix in the calcium form. The Benson BP-800 Ca is used for sugars and sugar alcohols and offers a robust alternative to less cross-linked calcium phases. The calcium form means that ligand exchange interactions are predominant, whilst the polymer matrix offers high stability in aqueous eluents. The Benson BP-800 Ca column is suitable for food analysis, sweeteners, carbohydrate profiling and routine sugar determinations.

Features and Benefits

• Polymer-based HPLC columns
• For sugars and organic acids
• Various counterions
• Ion exclusion and ligand exchange

Additional Notes

Benson columns are based on sulfonated styrene-divinylbenzene polymers with various counterions and degrees of cross-linking. The BP-100 series is typically associated with 6% cross-linking, while the BP-700 and BP-800 series represent more highly cross-linked variants designed for different selectivity and robustness requirements. Depending on the counterion, sugars, sugar alcohols, organic acids, or alcoholic byproducts are separated. Calcium, lead, sodium, potassium, and silver forms are primarily used for carbohydrates; H forms are typically used for organic acids, fermentation products, and related ion-exclusion chromatography applications.
