Benson BP-800 Ca Guard Column, 8%, 50 mm x 4.6 mm

The Bensons BP-800 Ca guard columns 50x4.6mm are used to protect Benson HPLC columns. Benson Guard Columns are pre-packed columns. No separate holder is required. The selection of the appropriate Benson pre-column is based on the series, counterion, degree of cross-linking, length, ID and the analytical column to be protected.

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.
