一般描述
All Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith® HighResolution 2 mm I.D. columns have macropores with 1.15 μm diameter, giving a column efficiency exceeding 140,000 plates/meter. The mesopores are 15 nm (150 ?), the surface modification is octadecylsilan with full end-capping.
The revolutionary, monolithic silica with its unique combination of macropores and mesopores enable:
-
Rapid separations at very low column back-pressure
-
High matrix tolerance, allowing time and cost savings with simplified workflows
-
Cost-savings due to extended column lifetimes
-
Connection of columns, flow gradients and the use of mobile phases with higher viscosity
-
UHPLC instruments are fully compatible with Chromolith® 2 mm i.d. columns
All Chromolith® HighResolution columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith 4.6 mm columns have macropores with 1.15 μm diameter, giving a column efficiency exceeding 140,000 plates/meter. The mesopores are 15 nm (150 ?), the surface modification is octadecylsilan with full end-capping.
