One of the World's Leading HPLC Columns

Dependable, ultra-pure silica-based HPLC columns that offer an extensive variety of selectivities which are scalable from micro-bore to preparative and purification scale solutions.

• Extensive line of rugged USP phases
• Wide pH stability for long column lifetime and method flexibility
• Easy method scalability from Fast LC to Preparative and Bulk Purification

Amino groups bound to the silica surface serve as a weak anion exchanger and offer polar selectivity under reversed phase and normal phase conditions.
